... and have some hives. Thats all thats happening though, have no other side effects, just the itching, its on my arms/shoulders , back, back of thighs. The pharmacists said to try benadryl and to watch in case anything else happens, but so far nothing else, just the itching and red skin. I have taken this before with no issues, so not sure what is happening. I am going to call the doc in the morning but am I going to be ok or should I head/run to an ER? Im a bit nervous here
