Hi,
My migraine attacks started about a year ago. First, I had a few attacks a month lasting 4-6 hours, but gradually the attacks became more frequent (occurring every week) and started to last a whole day.
My doctor prescribed sumatriptans for me, which seemed to work the first few times, taking the whole migraine away (the headaches didn't even start, since I took them right away when I noticed the aura symptoms). But now, after taking the medicine, it doesn't take the whole migraine away, but just mildly mitigates it. Furthermore, after a couple of hours, the medicine seems to wear off, and the migraine is back with its full power. Taking the medicine a second time after the migraine has come back fully seems to have no effect either.
Has this happened to anyone, and what course of action would you recommend me to take?
Thank you very much for your help.
PS. I don't think that the headache that returns is a medication overuse headache, because I have only taken sumatriptan 8 times in total.
