<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I am having these terrible headaches that I think are migraines. It feels like my head is going to explode, and I can hardly stand the pain.  <response>: I understand how tough migraines can be. There are several medications we can try to ease your symptoms. I recommend you start on Sumatriptan Imitrex to help alleviate the pain, as well as Topiramate Topamax to prevent future migraines.
