Hi, I accidentally removed the layer of skin on top of a blood blister, I immediately covered it in antibiotic ointment and it is currently wrapped in gauze. I had a plantar wart between my big toe and foot frozen. Last night I drained the blood and today while draining the blood the skin came off. There is still a little bit of skin around the edges. I am petrified of it becoming infected. I took off the gauze a little while ago and where the skin was missing the was like a dark purple/black section, which I think could have been blood drying. The wound is about half an inch. How long do you think it will take to heal? Should I visit a doctor on Monday?
