migraine
"Thank God for Imitrex. The first tablet I took stopped the headache and didn't have any side effects the first time. The next time I took it I felt shaky. The only side effect that I get from Imitrex is jaw pain. But at least my migraines are no longer in my back. Just make sure that if you are needing two 100mg tablets a day for several days in a row and you still aren't getting relief. Consider a preventive or have a backup. I don't have nearly as many headaches anymore."
