question: I saw a doctor two days ago due to painful swallowing. I had no other ailments, no congestion, runny nose, or sore throat, simply painful swallowing. The doctor checked my throat and said it looked like strep. I was prescribed penicillin, which i have been taking twice daily since. This morning, I noticed the palms of my hands were very red and covered in small bumps. What could this be? I have had strep before and was prescribed penicillin every time to treat it. Could this be a newly developed allergy, or a rash due to the strep throat? Thank you for your time.
