hello, i think i got a blood blister, possibly from sweating and friction. i went to bed last night with no issue, got up this morning and saw a purplish bump on my inner right thigh. not sure if i was bit by something or not. it started to pop , drained it somewhat , blood came out. not puss. the bleeding was not long lasting, as if an artery was ruptured. I bandaged it with gauze pad, washed it and put Neosporin on it. the nickel size elongated bump is now smaller, but similar in color. I may schedule with my doctor by calling tomorrow morning. I ve been looking online for remedies and possible idea on what it is. the very top of the bump blister had a small point, in the sense of it was harder and darker there, with somewhat of a peeling outer layer, as there was a faint perimeter of topical skin with white edges protruding. however, it is not hard to the touch nor painful, as when an ingrown toe nail occurs or swollen side of a nail bed with yellow pus and redness.
