Check with your neuro as well. There may be other options for you in regards to medications for both MS and migraines. Also, Shared Solutions might have some ideas as well and checking with them couldn't hurt.

While taking Aleve for relief when you do have a migraine sounds plausible, I wouldn't recommend it for everyday use. I would be concerned about damage to your stomach as well as to your kidneys and increased bleeding risk. Please double check that before you take 800 mg daily.

I hope that you find something that works for you for both your migraines and MS.
