What is this and will it go away? It has no pain, but I can feel it barely with my hand. I think it is a blood blister.
I should have mentioned in my other post that Mark Cucuzzella is also an MD, a BRS Ask the Docs’ doc. He will be with you shortly. Please have a seat.
It seems to be getting darker, so a blood blister is still what I think. It does not hurt at all even when walking on rough concrete.
