headache
"I had a severe concussion and was given Fioricet, after Toradol and something else wouldn't offer any relief. Talk about a miracle. Once it kicked in my headache was gone! One pill every 4 hours, but with my injury it seemed to wear off in about 3 hours and unfortunately it takes an hour plus to start working. I did sleep after each pill so maybe I'm just immune to the caffeine. Love this medicine, just wish it worked faster and lasted longer."
