Can I play basketball with these blisters?

Question:
Hi MyRunningDoc!

I have a basketball game tomorrow. Can I play basketball with these blisters without causing any problems?   What can put on it while I play?

Thanks!
JM

Answer:
Blisters under the ball of the foot can be painful. In the images above you can see that JM has developed some large blister that cover the entire big toe joint area. The blister may have started draining, or maybe he simply decided to pop and de-roof (meaning cut the blistered skin off) the blister in order to relieve the pressure. With large blisters, it is often necessary to drain blisters ton keep them from getting bigger. Yet doing so can make them more painful and take longer to heal.

In this case the raw pinkish area is going to be painful when running. Suddenly stopping or changing direction will also put a lot of stress on the blistered area and aggravate the raw skin under the big toe joint.

When you run, about 50% of you body weight is transmitted through this area. There are really only two ways to decrease the pressure to the ball of the foot at the big toe joint.

1. Decrease your activity (as in no basketball, walk less, etc.).
2. Move the pressure somewhere else. 

It is a simply rule of physics: you cannot remove pressure, but you can transfer it. It is possible to create a pad that moves the pressure from the big toe joint to the rest of the ball of the foot. By moving much of the pressure and irritation to the little toe joints, it may possible to play with less discomfort.

 

You can purchase pads at any drugstore that are designed for the ball of the foot. The idea is to hold the pad on the foot and identify the painful area. Clear pads obviously make this easier.

 The painful area is outlined on the pad.

The outlined area over the blister is cut away.

The pad now can put more pressure on healthy skin under the ball of the foot. The pad may stay in place well with a sock on. If not it can be taped in place to secure it. If properly placed, there will be less pressure on the blistered area. 

Even if properly offloaded, there is a risk that continuing to play will further erode the skin and cause more discomfort. In the end, if continuing to play on a de-roofed blister, it will take longer to heal. The increased mechanical irritation of running increases the chance of the blistered area becoming infected.

With any de-roofed blister (or other open wound) it is always best to seek an evaluation from your own physician before attempting treatment. You should speak with a sports medicine podiatrist to make sure that the blisters heal properly. You also need to identify the cause so that it doesn't happen again.

What is the Best Way to Diagnose Gout in the Big Toe Joint?

An attack of gout that affects your big toe joint may be one of the most painful conditions you can have in your foot. When gout strikes, you get pain, redness, swelling and extreme tenderness...usually in the big toe joint. If you think you have gout, you probably want to make sure that you get the right diagnosis. Getting the correct diagnosis is important for two reasons.

1. You want to make sure you get the best treatment as quickly as possible.
2. You don't want to have to change your diet and start the dreaded gout diet unless you're absolutely certain that you actually do have gout.

Gout is actually caused by uric acid crystals accumulating in the foot. The crystals actually get deposited as the precipitate out of your bloodstream and become embedded with in the big toe joint, a bursa, or even within the tendons near the joint at the base of the big toe.

There are 5 ways to diagnose gout in the foot
1. Physical exam by a podiatrist
2. X-rays of the foot
3. Blood tests to look for high uric acid levels
4. Joint fluid analysis from the big toe joint
5. Cytology (fluid analysis under a microscope)

This video, posted by San Francisco's Housecall Podiatrist, discusses all of the ways in which your doctor can arrive at a diagnosis of gout. Because gout is a condition in which uric acid crystals actually get deposited in the soft tissues of your foot in your big toe joint, it is important to actually identify those crystals in order to accurately make the diagnosis of gout.

Physical exam (even by a podiatrist) is not 100% accurate simply because gout also mimics other conditions such as an infection in the soft tissues around big toe joint, infectious arthritis of the big toe joint, or even conditions that affect diabetic patients such as Charcot foot, where the foot bones start to break. All of these conditions can present themselves with redness swelling and extreme pain around the big toe joint. Physical exam by itself is just not the best way to diagnose gout.

Foot X-rays are almost always performed in a doctor's office when you have a red hot swollen foot in order to make sure that you don't have a dangerous infection or a fracture in the foot that could be just appearing like it is gout. But x-rays of the foot won't typically show much when an attack of gout has recently started.

Blood tests in order to determine whether or not you are one of the patients that has a high level of uric acid in their bloodstream (and more prone to gout) are not really effective at determining whether or not the pain and swelling around your big toe joint is really caused by the crystals in your joint. In fact, often times these tests are negative, misleading doctors to think that you might not have gout.

A more reliable way to determine whether or not the pain in the big toe joint it's actually caused by count crystals is to perform a joint aspiration where the fluid is removed from the joint to see if there is any chalky white material that looks like collections of gout crystals. This is much more reliable than physical exam, foot x-rays, or even blood tests.

But by far the most reliable way to make the diagnosis of gout is through cytology. This is where your doctor takes the joint fluid that was removed through joint aspiration and then sends it to the pathologist so that they can look for the actual gout crystals under a polarized light microscope. If you do have an attack of gout that is causing the pain in your big toe joint, the pathologist will be able to see needle shaped uric acid crystals within the joint fluid. This is a 100% accurate method of diagnosing gout in the foot.

What Should I Do If I Sprain My Ankle?

San Francisco Podiatrist Explains How To Stop The Ankle Pain and Swelling When You Twist Your Ankle

Ankle sprains are the most common sports-related musculoskeletal injury. Unfortunately many patients who roll their ankles head to the Emergency Room to treat the pain, swelling and bruising. The reality is, you can often get ankle pain relief much faster if you don't go to the ER. When deciding which doctor is best for your ankle sprain, you should see a specialist: an ankle expert called a podiatrist (not a Jack-of-all-Trades in the ER).

The best ankle sprain treatment right after the sprain is P.R.I.C.E.

P=Protection
You have to prevent any further injury to the sprained ligaments. An ankle brace or fracture walking boot can let most ankle injuries heal without having to worry about hobbling around on crutches.

R=rest
If you get sick and rest, you get well faster. If you tear your ankle ligaments and rest, they heal faster. Try to get some rest and take it easy for the first 48 hours after a bad ankle sprain.

I=ice
Ice is one of the cheapest and most effective home remedies for an acute ankle sprain. Apply ice to your injured ankle for 10 minutes out of every hour during the first 24 hours after you roll your ankle.

C=compression
Use the elastic bandage given to you by Dr. Segler a your House Call visit. By keeping your ankle wrapped the way he showed you, the swelling will stop and go down as fast as possibly. Your ankle ligaments won't start to heal until the swelling goes away.

E=elevation
Use gravity to your advantage! Prop the injured ankle way up on a pile of pillows. It has to be above your heart to really work well. Keep it elevated for the first 24 hours and the throbbing ankle pain will start to go away. Remember, your ankle ligaments won't start to heal until the swelling goes away.

By following the PRICE method, you can help stop all of the inflammation that causes ankle pain and leads to prolonged healing of the ankle sprain.

Dr. Christopher Segler is a podiatrist and a true ankle expert. He published the largest research study every conducted on subtle ankle fractures that are often misdiagnosed as ankle sprains. The fact is, ankle injuries often don't get the best treatment in the Emergency Room. Dr. Segler won an award from the American College of Foot and Ankle Surgeons for his ankle injury research which showed that lateral process fractures are 10 times more common than previously thought. These ankle fractures often don't heal properly because they are incorrectly diagnosed by busy ER physicians. Dr. Segler now has a podiatry practice in San Francisco that offers same-day house calls for people in the San Francisco Bay Area who have ankle sprains or other sports medicine -related foot and ankle injuries.

If you rolled your ankle and have a question, you can actually call him directly at 415-308-0833. And yes, you will actually get to speak with an award-winning ankle surgeon. No nurses, students or residents... direct access to a true ankle expert.

To Pop or Not To Pop: Blister treatment for runners explained by San Francisco's Running Podiatrist

Dr. Oz recently ran a segment on his television show instructing his audience to pop blisters whenever they occur on the feet. He went on to explain that if you successfully get all of the fluid out, the top layer of the blister will form a adhere down to the tissue underneath and create a "biologic dressing."

While this may be sound advice for a typical healthy woman who gets a blister from a new pair of high heels, the real question for Bay Area runners is: "Should I drain a blister" if I am a runner training for a race such as a marathon or triathlon?

The best answer is "sometimes you should, and sometimes you shouldn't."

The medical term for the type of blisters on the feet when running are "friction blisters." Blisters on the feet occur from a combination of skin friction and pressure. When your foot slides around inside the running shoe, you get friction. Rubbing the skin over and over in one spot (such as the back of the heel or ball of the foot) causes the layers of the skin to begin to separate. Fluid then seeps into this newly created space between the layers forming the blister.

Keep irritating the area and the blister continues to get bigger. Even if you simply continue to apply pressure to the blister (like pressing it against the heel counter inside the running shoe) it will continue to get bigger. This is because the fluid will try to spread outward and keep separating the skin layers. Then even more fluid seeps in to make the blister bigger.

If you keep rubbing the blister long enough, the skin on the top of the blister will tear effectively popping on its own. The blister then starts to ooze relieving the pressure as the fluid leaks out. So should you take charge and drain it yourself?

What sports medicine podiatrists know about blisters in runners is:

1) small non-painful blisters heal quickly
2) large painful blisters hurt less if drained and not irritated, but hurt more and have a slightly higher risk of getting infected if they are drained and the activity (such as running) is continued
3) blisters with the overlying blister roof removed will heal, but hurt more initially

So If you are runner with a small blister on a toe and it doesn't hurt don't drain it. It will heal quickly and has a very low risk of infection. If the fluid can't drain out, bacteria can't get in. If you have a blister that is small, put a felt pad around the blister. You need a donut shaped or U-shaped pad for this to work. You need to put the pressure around the blister and not on the blister. This will stop all of the rubbing that could make the blister get bigger. It will also stop the blister from hurting.

If you running a marathon or competing in an Ironman triathlon and get a huge blister that makes it hard to walk after the race, drain it. You can do this by poking a small hole at the edge of the blister. Heat the needle or soak it in rubbing alcohol. This will sterilize the needle so that you don't introduce any infection causing bacteria when you puncture the blister.

Cover the blister with a bandage that will soak up the fluid as it continues to leak out. If the fluid starts to build up again, then repeat this process and drain the fluid again. Marathon runners with big blisters may have to do this a couple of times. The blister can be quite irritated after running 26.2 miles.

So what are the "exceptions to the rule" about popping or draining blisters in runners?

1. If you notice the blister at mile 13.1 and still have another half-marathon to go, don't pop the blister. This is where the advice from Dr. Oz doesn't fit with runners. If you drain the blister on your heel then continue to run, more fluid will seep under that skin. The skin will slide back and forth. If the drained blister skin slides around, it can't work as a "biologic dressing" because it never has a chance to stick to the underlying raw area. The roof of the blister may also tear. That is what happened in the blister pictured above. All of the rubbing of the heal inside the running shoe caused the blister to rip open. If the roof of the blister tears, it needs to be removed (called "de-roofing" by podiatrists).

If the blister is drained, you need to secure the overlying skin in place with a dressing. Wait until the race is over. If you drain it mid-race it will hurt like hell, there is a higher risk of infection and it will take longer to heal. You also need to wear a pair of shoes that won't rub on the raw blister after it has popped. So once you drain the blister, apply a dressing that will hold the skin securely in place. Change the dressing daily. Studies show that hydrocolloid dressings works best to bake blisters heal fastest. But there is NO evidence than antibiotic ointment helps blisters heal any faster.

2. All blisters should be drained, completely de-roofed and treated by a podiatrist if you are diabetic. The risk of infection is much higher in diabetics. A blister anywhere on the foot in a diabetic runner is a medical emergency. I have personally performed many amputation on diabetics where a blister became hugely infected and spread to the underlying bone. Seek immediate medical attention if you have diabetes and a blister anywhere on the foot, heel or toes.

Although it is easy to prevent blisters, they still often occur in runners. In fact research shows that blisters on the feet are by far the most common running injury reported among marathon finishers. If you get a blister on the feet, treat it right and it will heal quickly so you won't have to miss much training at all.

San Francisco Podiatrist Posts Video on 1 Hour Ingrown Toenail Relief in San Francisco

Ingrown toenails are easily the most common reason that a podiatrist will see a doctor for pain in the toe. Ingrown toenails can be prevented with some simple tips:

1. Cut normal nails straight across.
2. Keep your nails just shorter than the end of the toe.
3. Avoid shoes that cramp the toes.

The most common way people cause ingrown nails is by cutting them too short. This is often in an attempt to relieve a painful ingrown nail before it becomes infected. Unfortunately, this usually backfires. But even if you try to take it out and make the ingrown toenail worse, you can still get relief. This video explains how you can get ingrown toenail relief in San Francisco in only about an hour, even without going to a podiatry office.

San Francisco Podiatrist Explains Why Athlete's Foot is Common in Bay Area Runners and Cyclists

Athlete's foot is a fungus infection of the skin that often occurs in runners, cyclists and other athletes. It just so happens that the San Francisco Bay Area has a climate that can make it easier for you do develop a case of itching, burning, peeling feet that characterizes the condition.

In order for any fungus to grow best, it needs a habitat that is dark, warm and moist. As it turns out, shoes are perfect for this. You put on your running shoes and head out for a run through Golden Gate Park. Your feet sweat (even if it is fifty degrees), and the heat from your feet turns the shoe into a little incubator for the nasty stuff to grow. If it is like many days in San Francisco, you may even get some rain or light drizzle further soaking your shoes. Then you get home and toss your shoes in the closet until you get ready to go for a run the next day.

The problem is that very few closets have heat or air conditioning vents in them. For this reason, the shoes just won't dry out. They stay damp. And damp running shoes equals fungus.

Cyclists have a similar problem. Head out on the road to Nicassio or anywhere else in Marin county on the weekend and you will see hundreds of cyclist out for a ride. Most of them are wearing shoe covers to help keep their feet warm and dry. But these shoe covers don't breathe very well. As a result, all of that moisture gets trapped inside the cycling shoes. Once the ride is over, many cyclists will toss there shoes in the garage right next to their bike. Sitting in a cool and damp garage keeps the inside of those cycling shoes damp as well.

Sooner or later, the fungal spores in the shoes will cause an athlete's foot infection. Often this is just nothing more than mild peeling of the skin on the bottoms of the feet (see picture above). But some people get severe itching, redness and burning of the feet. Once in a while a secondary infection (caused by bacteria) can start an even bigger problem.

So what to do?

First off, it is very easy to prevent athlete's foot by simply drying your running shoes and cycling shoes out. Bring them inside. I usually leave mine near of a heating vent for a couple of hours after I go running or biking. This ensures that the insides of the shoes will stay dry. Dry shoes don't support fungus very well. If you wear cycling shoe covers, take them off after every bike ride to help them dry out.

If you do get athlete's foot, over-the-counter (OTC) anti-fungal treatment creams will usually cure the problem in about 4 weeks. All you have to do is follow the directions on the tube. Make sure you use the cream for about a week after the problem seems to have gone away. Otherwise you might still have some fungus in the skin that can flare back up in only a couple of weeks after you stop applying the anti-fungal medicine.

Keep in mind that if you get athlete's foot, you will have been shedding fungal spores in your shoes. You need to decontaminate them by spraying lysol in your shoes and letting them dry out thoroughly afterward. If the athlete's foot doesn't improve after you treat it yourself with OTC medications, see the best podiatrist you can find.
