chronic migrainer's 2 cents
Massage therapy is good. A chiropractor is either a good thing or a very bad thing - I've had both. One of my worst migraines ever was caused by a quack-o-practor. Fortunately my neighbor, who was trained by her chiropractor uncle, spent the next four days undoing the damage. I diagress...
When you're in severe pain, and you don't have meds at home, get thee to the ER.
I've found that good old phenergan (sp?) works. Considering most prescription migraine meds have limits on how many you can take in 24 hours or you run the risk of a rebound headache, taking a phenergan suppository helps. Yes it makes you drousy, but it knocks back the nausea, so you can hold down the water. Part of my migraines are brought on with dehydration, so it becomes a vicious cycle. OTC meds don't do diddly for me when it comes to migraine.
I've been put on various prophylactics, anti-seizure meds or anti-depressants depending on the preference of my doctor at the time. Both have worked, but daily meds can have side effects. It all depends on how often you have migraines, and how disruptive they become.
Have you determined if you have any triggers - foods, your period, weather changes, allergies, drinks? Some of them you can control, umm, the weather, not so much.
