as you know i have no way of seeing your hand or feet sores but hfm is a possibility although it is rare as an adult (assuming you are an adult). strep can cause desquamation (peeling of the skin) of these areas so it is possible that this process is starting. read about "scarlet fever". a person on antibiotics for strep would be better but you would also improve (naturally) if you had a virus like hfm. since you were not tested to know one way or the other the mystery may remain. if your sore progress you will need to see your medical provider again for a visual examination.
diagnosed with strep throat on antibiotic. now small sores are appearing on my hands and feet? what is this? . i went to the er with a sore throat white tonsils & fever. i was diagnosed with strep throat and prescribed an antibiotic but strep test was never done. 24 hours in to taking the antibiotic i noticed very small sores beginning to appear on my hands & feet. do i have hand foot and mouth? are there other viral things that could cause this? could this be a reaction to the amoxicillin? are hfam strep throat related? also no sores in my mouth and my "strep" symptoms have gotten better with the antibiotic.
