Hi everyone. 4 years ago, a week before the start of my senior year in high school, I had gone to a family friend's house with my family. I played soccer with some of my other friends that I was hanging out with, and everything seemed to be fine. The next day, or perhaps 2 days later, I woke up with around 20-25, pus-filled blisters on each leg, from the knees to my toes; the majority on my shins and calves. The size of each ranged from 1/2 to 1 inch each. Naturally, I was a bit freaked out and very worried. I know it's usually a bad idea to do so, but I tried poking the blisters with a needle, but within a few minutes of the pus coming out, the blisters rehealed and filled with pus again. I went to my general physician as soon as possible, and, when poking the blisters with a needle failed, he ended up just cutting the blisters off completely with a pair of scissors (very painful). Needless to say, coming to school in 80 degree weather with shorts and legs bandaged up like a mummy for the first 2 months of my senior year was decently awkward. My doctor thought it may have been erythema multiforme, and suggested that I see an allergist. However, my allergist said that there was a possibility that it was erythema multiforme, but she wasn't sure because she had neither seen nor heard of a reaction like mine and said it may be some unknown allergic reaction. I don't know too much about erythema multiforme, but from the pictures I've seen on the internet, I'm quite convinced that what I had was completely different. Has anybody ever had anything like this before? What could it be? Any help at all will be much appreciated!
