[|Human|] My teenager (daughter) has a rash on her torso with some spread to her back and arms.  Its been going on for a while but has gotten worse.  It itches badly.  They are tiny bumps, lightly red.  At first it looked like perhaps a bug bite but since they appear at all times and are spreading that doenst seem likely.
[|AI|]  Hello. Thanks for writing to us at Chat Doctor Extremely itchy rash/bumps involving the trunk, arms and legs can be due to scabies. In scabies the lesions resemble insect bites and are distributed over the torso, arms and legs; specially inner thighs, maxilla and chest, finger webs etc. Family history of similar lesions and itching can be a significant clue towards scabies. If I was the treating doctor I would like to treat her empirically for scabies with Single whole body application of 5% Permethrin lotion, kept overnight for 8 hours, followed by scrub bath next day. An OTC oral antihistamine e, g cetirizine 10 mg once daily would provide symptomatic relief from itching. Regards
