Hi all. About 10 days ago, I had what seemed like a bug bite on my leg. A couple of days after that they turned into little blisters. Now for the past 4 days, they've grown into larger blisters. They constantly leaking clear fluid. No pain/tenderness or other symptoms. I went to the Dr.'s and he said he didn't know what it is, but he's going to treat it as impetigo. So I'm on antibiotics right now, but it doesn't seem to be helping. I've posted some pictures. The black markings were drawn by the Dr.
