Is That A Pebble In Your Shoe?

"Is there a pebble in my shoe?"

We’ve all had it happen. A little pebble or stone gets lodged in our shoe and we can not continue walking until we get rid of it. So what happens when you take your shoe off and there’s no pebble in it? You may have porokeratosis.

What is porokeratosis???

Porokeratoses are sweat glands that are plugged up with callus tissue. They are hard calluses that form on the bottom of the foot. They are typically about the size of a small seed. Oftentimes, porokeratoses feel like a pebble in your shoe. They usually occur on the bottom of the foot at the ball of the foot or the heel.  They are also known as  “seed corns”.

There are about 300,000 sweat glands on the bottom of the feet, so there is a large chance for at least one of the sweat glands to become plugged.

These lesions can become painful and feel like there is something stuck in your foot. Also, if an individual has very little fat padding on the bottom of the foot, they may experience quite a bit of pain from these.

I can treat these in a variety of ways. Usually I will attempt to gently core out the porokeratoses with a small bladed instrument. It sounds worse than it really is!
