Treating a Blister Under a Callus

April 25th, 2016

Circle of Feet on GrassWe put our feet through strenuous exertion daily. When friction created by socks wears away at a specific spot, it causes fluid to collect between the upper and lower layers of skin, forming a blister. The blister forms to protect your skin from further damage but when a blister forms under a callus, rough protective skin that acts as a defense mechanism, you will need to see a podiatrist to treat this more complex problem.

How Does a Callus Develop Under a Blister?

Usually, calluses protect skin from blisters because they shield your foot from the pressure and friction responsible for blisters. If you do not remove the callus and the friction and pressure continue to rub on your foot, a blister will form under the callus as additional protection. While blisters are not challenging to treat on their own, if one forms under a callus then you will need to go through several layers of callused skin to care for the blister.

Treating a Blister Under a Callus

Plano patients should not pop blisters under any circumstances. A blister under a callus will be particularly painful because you need to get through multiple layers of skin to drain it. Doing this on your own opens the blister up to infection and related complications that can seriously damage your foot.

When to See a Podiatrist

If your callus is deep, then the blister cannot be safely treated without the help of a podiatrist. Complications such as cellulitis and sepsis can arise from an infected blister. A podiatrist can help you by:

  • Treating your callus and the blister underneath it with sterilized instruments to prevent infection.
  • Providing you with tips for prevention and techniques to manage friction and pressure to your feet when you’re exercising.
  • Ordering custom orthotics to evenly distribute pressure and take weight off the callus and blister.

Dr. Verville treats Plano patients for a variety of foot and ankle problems to reduce pain that causes lifelong issues.
