I've read on this board--and elsewhere--that fibromyalgia usually is triggered by some kind of trauma or illness. Although I have multiple sclerosis, I've had it for years, but my fibromyalgia was just diagnosed 5 or 6 weeks ago. I've also read about a possible connection with mycoplasma. I had mycoplasmal pneumonia, but that was 14 or 15 years ago, and my doctor says he doubts whether the mycoplasma still would be a facor. I do get myoclonic jerks in various parts of my body, associated with my MS. Ten years ago, it was extremely severe, then it went into partial remission, and then three or four months ago, it came on strong again, this time more in my arms than my legs. Occasionally, the jerking also affects my neck. My husband was wondering whether if the jerking was severe enough, this could have triggered the fibromyalgia. My doctor didn't have any idea. So I'm asking you. Also, I've read a lot about fibromyalgia flares. I'm familiar with the concept of flare-ups and remissions, because that's how relapsing-remitting MS works, too. But I seem to ache all the time--just a little more some days (or some hours) than others. I don't seem to have the degree of pain that a lot of you seem to have, but it's certainly more than enough to deal with! I'm definitely still in the learning stages with fibromyalgia, though I've been reading a ton and will be leaving soon for my second fibromyalgia class. I would greatly appreciate any information you can share. --Laura R.M.
