Have welts on my forehead and around my eye. Also had a severe head ache. Went to dr. yesterday. Was given a steriod shot, told to take benedryl and prescribed tramadol for pain. He said it was an allergic reaction to hydrocodone cough syrup. Tonight I am not better. The welps are still there and the pain is now concentrated in my eye. Should it be taking this long to clear up or at least get some better?
