Need medicine for a migraine i've had imitrex (sumatriptan) and a shot injection but don't like the side effects of either is there anything out now thats better?

Absolutely.: Other medications include zomig, (zolmitriptan) maxalt, Amerge and others. Side effects vary from one medication to another and person to person. You could also consider medication to decrease the number of migraines, but only if they occur often enough to take something daily.

Many options: There are many different abortive medications available, including triptans (like imitrex), fast acting nsaids, and others. If you are having headaches frequently enough to warrant daily medication, there are medications that can reduce the frequency and intensity of migraines. A neurologist can help you find the best treatment for your individual case.

Headache. Pain: Pain is a process of repeating questions, reexamining, testing blood, doing studies (x-rays ct MRI eeg...), trying combination of meds. Time to figure out response (sometimes we change meds too soon) time for a particular diagnosis to manifest and treat accordingly. The more your doctor knows you the better for you. It's challenging, but is duable. Best of luck to you and health.
