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.

Can I Continue Running With This Blister?

We receivd an email inquiry from Julie who is currently training for a marathon. She recently injured on of her little toes and wants to resume her training.

She explains. "I have had this blister now for a week. I had also tripped over a bike rack which bruised my toe as well. I am on antibiotics and they took X-rays to confirm my toe was not broken. It was not broken but very infected. I was training for a marathon and want to know if I can continue running or do I need to wait longer for it to heal."

As a sports medicine podiatrist the primary concern with a blister is of course to help the blister heal as quickly as possible so that the patient can resume marathon training without any significant loss of fitness.

The basic tenets of blister treatment involve the following:

1. Provide mechanical protection of the blister. This means to use any combination of reduced activity, shoe modification, padding, etc. to stop rubbing and irritating the wound. If you continue to apply shear forces and friction, the blister will take much longer to heal, and could even get worse.

2. Optimize a moist environment of the wound to facilitate healing. This means that you want to keep the wound properly hydrated. The wound has to be moist, but not too moist. If a blister is actively draining, the dressing should absorb the exudate to prevent the excess moisture form breaking the tissue down further. If the wound is too dry, then a dressing should be used that will add moisture sufficent to promote healing.

3. Reduce the bioburden of the wound. "Bioburden" is a term used by wound care specialists that refers to the well-know negative effects of bacteria colonizing a wound, or worse yet, infecting a wound. Your skin is covered in bacteria. This not a comment on hygiene; it is a natural state. Any open wound will quickly become colonized with bacteria as well. If there is an excessive amount of bacteria feeding in the wound, the wound healing process slows. Many wound care products are designed to impede the growth of bacteria or wash the bacteria away. But not all are created equal. Some commonly used wound-cleansing substances such as dilute bleach, hydrogen peroxide and povidone-iodine kill off bacteria, but unfortunately are also toxic to the cells trying to heal the wound at the base and edges of the blister.

Much worse than a "colonized wound" is an "infected wound." The difference is that an infected wound is one where the bacteria is actually directly damaging the tissue. This is the case described above.

It appears from the picture and description provided that this runner's toe has not been caused by the exceeding common friction from running shoes, but is in fact a traumatic injury, more likely causes by a direct blow when tripping over a bike rack.

When this kind of injury occurs two things can happen.
1. The toe (or at least on of the phalanx bones within the toe) can easily break.
2. The nail plate can become separated from the nail bed leading to a nasty infection.

This type of injury has to be treated much differently than a standard friction blister.

The first concern is to treat the infection. This might be accomplished through the administration of prescription oral antibiotics, drainage of the blister and removal of pus in a podiatrist's office, and perhaps, even remove of the nail plate. Deciding which of these are appropriate would require an in-person evaluation with a podiatrist.

The second concern is the possibility of fracture. Little toes get broken all the time with the kind of injury described. The reason this is so worrisome is that if one of the bones in the toe is broken, the infection in the skin and surrounding soft tissue could easily spread to the bone resulting in osteomyelitis- also known as a bone infection. Bone infections are serious and are the primary cause of amputation of toes.

Before returning to running this runner (and her doctor) would have to be certain that the toes wasn't broken and the infection was well on its way to healing. Once that has been accomplished, it would be necessary to have a podiatrist who treats runners often evaluate the runner's shoes and determine the best way to offload the toe so that it could continue to heal with any irritation. She should then be able to get back to training for her marathon.

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.
