Multiple headache sources

[untonuggan]

My most recent migraine was a doozy that kept me off the computer for awhile. I think one of the main triggers was a TMJ headache caused by opening my jaw wide at the dentist. My worst headaches are usually combos, such as when I get really tense and the pain just migrates from my neck to the rest of my skull. Allergy/sinus flares can quickly evolve into the mother of all headaches.

Once these set in, I find them really difficult to shift, perhaps because I can't just do what I would do for "just" a migraine or "just" a sinus headache.

How do other people deal with having multiple headaches that merge into one horrible beast? Better yet, if you know you have a sinus headache, how do you prevent it from mating with other headache triggers?
