### input:
I ve had a bump on my leg for years. Every now and then it itches and the top layer of skin will slough off leaving a red exposed wound. It only bleeds if I squeeze or pick at it, but I can tell it s an actual hole and when the skin heals there is still a bump, but the last month or two it won t heal. It scabs over, but itches and if the scab comes off there is just a hole that oozes clear, sometimes red. But it won t go away. It keeps busting open, then healing, then busting open again. I can see under the layers of my skin. It s the size of pen tip just about.
