Have a rash on my nake when I first seen it look like a wingworm now it looks like bug bit that just keep getting worse and a few on my arms now?

Does it itch? It can be a bug bite which can get larger for days after. If this gets worse, see your doctor. If it itches, a topical Hydrocortisone cream may help. If it shows pus later on, then it is likely from a spider bite which needs be treated with an antibiotic.
