hmm that's interesting. it's been 3 weeks since i started ritalin and now i experience a burning pain in my left arm muscle. without any activity.
could that be fibromyalgia or an increased autoimmunity by the ritalin?
Here's a synopsis of what I've been discovering, in case it triggers any useful ideas...
For a long time now I've been puzzling over the dopamine-chain connection to my FM/ME.
I have neuropathies (small-fiber, peripheral, and autonomic), so, with me, my daily pain would usually progress from numbness and tingling (usually left-side dominate, but not totally; worse in the limbs and extremities). Through the day, as fatigue would set it, the tingling would turn into burning -- often all over, but, again, the left side got it the worst. The burning felt like a sunburn about a half-inch below the surface of the skin. Or maybe a bad niacin flush that doesn't go away.
Anyway, duloxetine (60 mg/night) takes the edge off fairly well. (Without it, I felt like I had the flu.) But, since everything gets worse in the evening (including bad RLS, arm flings, etc), I rely on cannabis before bed, as that's the most reliable med I've found to relieve the feeling of pressure building up under the skin.
I once read somewhere that males with FM often experience their pain more as burning and less as deeper myalgias (and tender points). I don't know if that's true, but over the past half year I've been getting severely debilitating myalgias that I first thought were injuries, but that the physical therapists are now attributing to FM. Meanwhile I've been getting less burning. So my working theory is that my FM has been evolving (or devolving?) into the joints and muscles more. Constantly stretching out those tissues seems to help (also traction/distraction maneuvers).
Anyway, the fact that I have such trouble tolerating tweaks to the dopamine chain makes me
feel like I'm allergic to dopamine. So I
feel like my body is relying instead on other forms of energy (glutamate, stress, adrenaline), leading to extreme fatigue and sickness.
I may be way off base with this theory, but I have been getting some positive results with n-acetyl cysteine and other supplements that promote healthy GABA-to-glutamate conversion. NAC is one of the few supplements that I really notice when I skip it.
I did well with bupropion (as a stim) for about six months -- making me think the problem was with dopamine-to-norepinephrine conversion (since bupropion targets norepinephrine mainly), but suddenly, one day, it stopped working and just left me with burning and fatigue. I'll try mini-doses one of these days, as I used to like it.
The biggest challenge with this stuff is that everything is always changing. As soon as you think you've found a stable protocol it's likely to abandon you. Or, at least, that's been my experience.
