I have had this horrific rash since 5/24, which started with bump on my back that itched badly and frank said looked like a spider bite. It spread to shingle type blisters in a vertical line by 4 days. Primary doc said some kind of virus and have me steroid cream. Got worse, spread to legs. Doc took culture, not viral, appt with dermatologist. Got an emergency appt with neurologist who said couldn' be reaction to Capoxone because not on subcutaneous level, but dermis level ( or something). Dermatologist took byopsy (OUCH) and results came back as a bug bite! Use bug repellant when going outside, continue with steroid cream. But, I now have in various stages, size and locations, 84 whelps or blisters(some in a cluster the size of silver dollar), or hard bumps, horribly itching. I do not work outside in my garden, or pick the blueberries, or just pull weeds around tomato plants cause he said it was outdoor bug bites. We stripped all the bedding and searched carefully for bed bugs I wash all my bedding in hot water due to allergy of mites. Has ANYONE had serious skin (starts itching before bumps or whelps appear) just sitting in various places. It does not get worse at night. Anyone had any problem like this with MS???? Allergy results 6 yrs ago came back 3* for mites but photos aren't like mine!
