headache
"This medicine is a lifesaver! I have TMJ moderately severe, sinusitis frequently, and also am an anxious person. I had a headache for 3 days after working out strenuously at the gym (probably triggered my TMJ pain). I just took one dose (1 pill of Fioricet) and 20 minutes later, bingo! no headache! Even with jumping up and down, no headache! It's totally amazing and wonderful."
