I have itchy, flesh colored bumps on my foot. They itch like crazy, ridiculously, some are clustered, some are spread out, its kinda random. I recently had a nasty spider bite on this foot, at least, what i assumed was a spider bite, that is mostly better, just a little red around that area, but now i have these bumps and they itch like crazy. I accidentally popped one w/ scratching (bad, i know, to scratch, but i feels a little better when I do. ), and they are fluid filled. I'm going to the doctor on tuesday, but was wondering if anyone had any idea what is wrong with me? I also found some hives-like bumps on my knees, similar to what these looked like two days ago when they first appeared. Thanks!
