So I've been doing this for about 4 weeks now (2 to 3) times per week with a week off when my doctor went on vacation, and I am finding the results very promising. It hasn't 'cured' my headache, nor did the doctor say that it would...he said some patients find they have few or no more headaches right away, some find that they get a significant reduction in pain and frequency (what I was aiming for, I don't expect miracles anymore) and for a smaller percentage they unfortunately have no effect.
My migraines are -not- always behind the eyes/in the front...usually I have some pain behind the eye and in the temple but it also travels down the body to settle in the neck at its worst, and sometimes into the upper back as well. Just sort of a wall of pain that wants to be everywhere but my shoulders on up. In addition to the SPG treatments (which are painless, no big deal at all) He recommended me for PT at his practice to strengthen and stretch back and shoulder muscles, and gives me lidocaine 'shots' (they actually come from this weird air-gun thing) in the neck and upper back to loosen muscles.
I'm optimistic, mostly hoping this will help me cut back on Triptans and rescue medications, as all of these treatments are considered 'medication free' and not potential contributors to an MOH cycle, or likely to mess with anything central in terms of side effects, its all just localized.
I'd recommend giving it a try to those who are curious, and to anyone in the DC/DC Suburban MD/NoVA area who wants a particular recommendation, to check out this place, it is very caring, focused, and knowledgeable about headache in particular for a specific pain management clinic.
