I was taking Amoxicillin for Strep throat and 8 days in I got an itchy rash that quickly spread to my whole upper body (lower body only light rash). I'm in a third world country. What should I do?

It should improve on its own in a few days. If the rash does persist, or any new symptoms, seek medical care. ...Read more
