Many of our patients come in with calluses on their feet, some painful and some nonpainful. But one specific type of callus that causes significant pain – a feeling of walking on glass – is called a porokeratosis.
There are many forms of porokeratosis, but what we commonly see is a callus lesion with a core that extends deeper than the superficial skin layer. This deep extension causes increased pain, and it only gets bigger and more painful with time.
This type of skin lesion is commonly mistaken for a wart.
The cause of these lesions is not fully known, but have been associated with excessively sweaty feet and chronic pressure points on the bottom of the feet.
Treatment includes debridement of the lesion in the office, which involves removal of the deep core. Topical medications are then applied to help remove the lesion and medicines to apply at home to dry up the lesion and slough off the dry skin.
The underlying condition leading to the development of the lesion should be addressed as well. This can include treating the sweaty foot condition or addressing excessive pressure points of the feet.
Remember, pain in your feet is not normal. It’s your body’s way of telling you something could be wrong. Visit your podiatrist at the first sign of trouble to avoid continued pain and grief.

My feet constantly feel like I’m stepping on glass I soak them and use. A callus remover but pain is getting worse
It’s like everytime I walk I get a shard pain as if there’s glass stuck in my foot, god it hurts
Get a safety pin burn it in dig it out
Shantelle, I tried what u said but it’s been 3 months of recovery for me since I dug in there with the safety pin. I made a huge hole around the callous to get it out but now it seems the callous grew back bigger to fill in the hole and it’s keepig me up at night, what do I do with no health insurance from home
I had the same problem a few years ago. I ended up with 5 of them!! Digging out the core made it worse for me. In the end I used Salicylic acid for warts every morning & night for a few weeks and also duct taped over them. After a week or 2 they stopped hurting and after a while I managed to squeeze the whole thing out.
Stepped on a glass 8 or so months ago , heard a crunch and then pain . I’ve dug out nails , thorns , splinters and glass before . This time was definitely different! Thought all glass was dug out ,put band aid and waited for a week or so . Still fills like glass in my foot. My wife did her thing and low and behold more glass , I said great now I’m gonna heal! Week later still fills like glass. In time and months my oldest son , my youngest son and my daughter alone with me digging into what still fills like glass . Bare foot now it’s impossible to walk on . It’s so sore it keeps me up at night. Dermitoligist dug at it , it began to bleed she thought it looked like a wart. I’m off now to a podiatrist.
I have this little hole deep under the skin in the bottom of my foot I don’t know why it happened but it only hurts when I specially put pressure on the part of my foot it’s on and it happens to be below but in the middle of my pinkie toe and the one next to it don’t know if it’s the deep callous lesion and I should see a doctor or what could really use some insight
