i have what i first thought was a blister on the left side of my pinky toe. Then I thought it was a blister in a callus. THen I thought it was a wart. I cut inside it. It bled like a wart would. I had been burning and rubbing against my 4th toe I play a lot of tennis. I have never had this before. it was like a perfect circle. now the part that hurts is the hard skin around the surface inside. That part doesn t hurt anymore and has smoothed out. it is the outline. i am putting bacitracin on it and a corn bandage (no med) what do i do
