5 days ago i got this huge high bumps, one in my
scalp, and the other two of 3 next to each other
on my back, with a big red plake of around 5 CMS. They're itchy and burn at times, but are receiding well, and mostly gone. I've had two situations of allergic reaction to insect bites and thought this could be another, as i noticed i have fleas or bedbugs this morning. I was bitten on my feet a lot, but no allergic reaction...is this normal, for ones to react this way and other don't...
