"agressive chiropractics" and this began? where you perhaps seeing the chiro for fibromyalgia in the first place?
18 yrs ago, I reached for a cupboard door then couldn't lift my right elbow above my waist for over 5 months. One day that pain just went away, leaving only the weakness from not being able to use my arm ... everything eventually righted itself.
Drs didn't even know fibromyalgia back then, but no matter, I wasn't doing drs.
Google fibromyalgia, look at this strange set of seemingly unrelated symptoms. If you decide that you do have it ... you can try what worked for me: MH''s plant iodine. In the meantime, try Spray 1 for the pain.
