A little under a week ago I noticed my foot was itching like fuck, so went to scratch it and immediately noticed an inch and half wide, quarter inch high lump just above my toes. It seemed to be fluid under the skin, maybe with a slightly harder area at one end of it.I assumed it was a bad reaction to a spider bite or something and put it under ice. The lump decreased steadily over the next 24 hours until after 36 hours it was completely gone, leaving only a spreading, fading ring of painless bruises which have almost gone.After 2-3 days of absense, the swollen lump has mysteriously returned. This time only half as wide as before, and about as high. and height, and I ve put it back under ice, where, over the last hour, it appears to have decreased slightly, just as the previous one did.Have I misidentified this as a bite? Or is it just a case of the same allergic reaction occurring to a now lesser concentration of the same venom?
