Someone told me maybe from advil, so I switched to Tylenol, but hives came back. Someone else told me maybe from Tylenol
, so I switched back to advil (when I get headaches) and
I still got hives. Could not match the hives to times I took either Advil or Tylenol, or when I was menstruating or not. This past month, got period twice and hives twice, second one worse than the first. Benadryl allowed me to sleep but hives still there.
