CDC,I feel almost identically to you. I have the occasional good day, but most days now are a battle to feel normal. I haven't been down the neurology road for very long, but long enough to have had the standard EMG, Brain MRI, blood work for Lyme, B vitamins, thyrdoid function test, cortisol levels, etc.. Just had a sleep study last night by request from the neuro who suspected sleep deprivation might be the cause of my tremor / trembling. Nothing doing, not even sleep apnea (which I thought was a guaranteed money grab for one of those c-pap units).Its hard not to go to the PD, MS websites and find many symptoms in common; it kills me some times. Neuro says my tremor is too fast to be PD, next step is the spinal tap for MS. With a clean brain MRI I am hoping I'm in the clear; but even if I am, I'm finding it hard to believe this whole thing is benign. My left arm is completely dead now in the mornings and I am waking up to that dead arm 2-5 times a night as well. Fingers are numb a lot during the day and my hamstrings feel like they are old elastic bands that can't flex anymore. Constant dull ache.You know, I think what may be worse than all of the guessing and fear, is that to the outside world (my wife included) it looks like my fingers tremble slightly and it doesn't seem like that big of a deal. I wish I could 'beam' people into my body for a little ride (so to speak) and then see who runs to google at 4am when they have to beat their arm back to life!While I have read many posts here that give me hope that this is benign, its hard. I have great empathy for everyone on this site who is dealing with any of these symptoms. I really thought I'd go to the doctor, get my antibiotic and be back on track in a day or two. I've only been at this for 3 months, but it feels like forever. I know this may not help anyone; and if I get a diagnosis, good or bad, I'll post it and hopefully help people get answers of their own. Until then I am just glad to have other understanding people out there, and to let others know I'm here too.
