Count me in. LAK, James and Sue, I am so sorry you deal with headaches, they are truly horrible to endure.
I have had migraines for a few years now (it is a whole body disease, not just a headache), but have not found a migraine med which helps. Took a flexeril last night and it did not even help. Not taking NSAIDs because they had a horrific rebound effect when I stopped them, trying to detox.

Shortly after being diagnosed w/AS & fibro, I got a different kind of migraine than before - one with a crunchy neck and muscle spasms (dr (GP) said a huge muscle was in spasm - could that be the occipital muscle you refered to, Sue?) Now I get these 'new' migraines w/the cracking, crunching neck & neck spasms all the time. This current one I have had over a week and I am sick of feeling hungover when I wake up and all day long. The only feedback from my rheumatologist was 'the AS is affecting your neck now'.

Interested in the ultrasound machine, would love that info.
And lidocaine sounds interesting too.
Best wishes for relief asap for all of us!
