Hi I have had a rash for over a week -- began as a single very itchy small spot on my wrist/hand that seemed like a bug bite -- spread to arms and then legs - from mid-forearm to mid upper arm and corresponding area around knees -- itchy red little bumps, splotchy red spots, and now multiple small black and blue marks in rash area on legs. Thoughts??
Hi, It seems that you are having lichen ultimatum, also known as popular urticaria. It is hypersensitive reaction to insects. There appears erythematous popular lesions with mild to severe itching. Take short course of steroids in tampering dose. Take antihistamines till itch is relieved. Take antibiotics, if there is secondary infection. Avoid soap bath. Try to protect from insects. I hope you would be benefitted. Best health wishes.
