I am so sorry you had to go through that crap! I have been there. Wondering whats going on with MRI's, they have seen something, then they didn't, let's poke 'em in the spine and check that fluid out... Very frustrating (beyond that). I hope you find relief soon. My headache was (and somewhat still continues to be) more tension style. Stiff/sore neck with dizzy spells.
