<s>[INST] I have this itchy, goosebump like rash on my face, shoulders, chest, back and arms. I've had it for 3 days. I've tried Ito think of things I've done different for the past few days but I can't think of anything. Do you have any possible idea of what it could be? [/INST] Hello,I read carefully your query and understand your concern. Your symptoms seem to be related to an allergic reaction.I suggest using Cetirizine 10 mg daily.
