Breathe, I'm in the same boat as you with chronic headaches...tension/migraine and sinus. Usually the three kind of meld into one another so that it gets difficult to tell if you have one or all three happening.I have run the gamut of remedies..masage, chiro, cranio, acupunture, etc...all supplied some relief, but never long term or permanent.Imitrex does knock out the migraines, but doesnt' touch the other two.Surprisingly enough, the one thing that did reduce them long term was botox injections. I had heard that it was a side effect of thsoe going in for beauty treatments.....and there was a Dr in town trying it out so I went for it. Darned if it didn't work...takes a while to start working but my migraines were reduced about 80% for about 4 months after only one treatment.Down side, very expensive ( about $300 -$600 per treatment) and lord knows what teh long term side effects may be. I have not been able to afford to go back in again and yes, my migraines are back full force.Mine are brought on by hormones and weather.
