Today is Friday. Last Monday I noticed my shin itched terribly so I scratched it rather vehemently. Soon after, I saw that there was a bump on it (like a mosquito bite) and that I had scratched the skin off (and there was fluid on it). The abrasion scabbed over by the next day, but I noticed that the redness had spread about a centimeter. It wasn't really circular like I would have expected a mosquito bite, but more splotchy. By the end of that day, that area had become raised and itchy just like the original area, while the original area had darkened slightly in color and appeared to be on its way toward healing. Every day since then, I have developed one or two new "bites" on either one of my legs. I don't know if they are really mosquito bites or not, because I don't know how I keep getting them. We had some mosquitoes in the house a couple of weeks ago (I saw them and got bitten a couple times) so I suppose it is possible, but does this sound like the normal course of events for insect bite healing? The original area that I scratched is still red, although most of the "swelling" in it is gone (still itches a bit). The other "bites" that I didn't scratch to death look just like regular mosquito bites - pink, fairly circular but some with vague perimeters, raised and itchy. I'm starting to get freaked out. I am a reasonably healthy 35 year old female, (at least I think I am) except that I suffer from anxiety disorders. I am allergic to feathers, dust, staph, and mold, but I can't see how that could possibly be related. Is it possible my down comforter (that I just pulled out of storage) is the culprit? My husband doesn't have any mysterious bumps and he sleeps in the same bed. We have a cat, but my husband says he checked her for fleas and she didn't have any. I don't have any other symptoms to suggest any illness - no fever, no nothing. I am totally stumped and worried about what is going on. Could this be something serious? I appreciate your assistance! Thank you.
PS - The bumps don't hurt, aren't warm, aren't filled with pus or anything like that, and don't have visible bite marks.
