i had an injection of torodol im for a migraine. it did not help the migraine . but approximatly 12 hours later i developed a rash on both my upper arms with itching [[[[[[hives]. my right side broke out as well but just with redness. i'm concerned. the only side bothering me noe is my right arm with itching, and hives. i don' believe it's a symptom of the shot. i have shingles this concerns me. is there any chance these are some of the symptoms? HELP!
