I have a blood blister on the pinky-palm callus of my right hand. I have had this for months. Anytime it breaks open it bleeds persistently for hours. I do lift several days a week without gloves, so I imagine that's how it started. I cannot get it to go away. It will recede and slowly seem to be covered by the callus, but eventually it will resurface and burst.
I'm a typical stubborn man and I've tried to fix it myself by digging it out with a small knife or needle, freezing it off with dry ice (when I thought it may be a wart), and I've tried to cauterize the wound with a battery-operated tool meant for burning off moles. When I have dug into it it feels to be a few mm deep.
I've gone to a NP at work when it was bleeding and explained it to her. She seemed to think it was a re-directed blood vessel from my years of lifting and pinching the area. She said most likely it isn't healing because it isn't able to properly heal from the bottom out. She said it would need to be packed to heal properly.
Any suggestions? Its such a silly thing to go to the doctor for, and while I have great insurance I don't currently have a PCP so the whole process will take forever unless I go directly to ER where I bet they will simply bandage it and move on.
