What have we here? A little surprise, the other day.
There are three names for this: vascular or hemorrhagic callus, and extravasation (that's the fancy medical word). This was hiding under a very thick callus. It's not painful, but it can become a really big pain in a hurry.
This is the precursor to a foot wound. It's caused by pressure on the callus, which makes blood leak out into the tissues in little splinter hemorrhages (petechia) - those red spots. If the pressure continues, a "blood blister" forms between the live skin and the callus, and then the skin underneath this blister starts to erode, causing a wound (ulcer) that can't be seen. This is particularly dangerous for people who have diabetes, poor circulation, limited feeling in their feet, or a lowered immune system. The sad reality is that the eventual outcome of this is often a toe amputation.
Happily, this person came to Sole Focus for care and with regular attention this will heal up with no problems. Want to know more about managing calluses at home? See our post on cracked heels at https://www.nakuspfeet.com/post/cracked-heels
Moral of the story: calluses aren't always a good thing! Check your feet regularly or have someone check them for you. Don't let calluses or corns get out of control. Foot care nurses are here to help keep you on your feet ... and on all 10 toes!
