What Is My Problem?? Pls Help

It started a couple of months ago. Thought it was stress, maybe it is, I dunno. My back started twitching really badly. Not as bad as muscle spasms, not visible to the naked eye but all over my back individual strands of muscle/fiber/nerves started twitching.

It has gotten to the point now to where my sides, back, legs, arms, face and torso are in a constant state of twitching. It feels like someone is tickling me - all of the time!
Some of my symptoms include:



my hands are always shaking like a dang leaf

individual parts of my body feel impossibly heavy

i can't think coherently

i've lost close to 25 lbs in 2 months

i can't sleep more than an hour at a time and normally go for a couple of days before exhaustion finally, mercifully kicks in

nausea

vomiting

diahreaa (sp?)

i feel as if i'm going through life in a dream-state. Everything is hypersensitive

a few weeks ago I had a cold and since then, the cold went away but my head feels ... Open. As if you took over-the-counter non drowsy cold medicine but I haven't done so. My head doesn't hurt at all but it feels like it's going to pop, like the sinuses are going to pop. Related? I dunno.

Constant (i mean constant, I can't even undo them when I concentrate!) tight muscles in my jaw, legs and back.



That's my symptoms that I can think of at the moment. You gotta understand that everything else is secondary to being tickled. It's like having a migraine. You can't stand having light in your eyes but your head exploding is your main problem.

I am on disability and can barely afford to pay rent (literally) so going to a doctor is out of the question. If I absolutely have to, i'll find a county doctor or something but i'd like to at least be able to have something to tell them other than i'm being tickled. I've been to the emergency room because I passed out from hyperventilation but they just gave me oxygen, an iv of glucose (?) and watched me for a few hours. No idea what is wrong.

If you have any idea what is wrong, please help. I have searched the internet but cannot figure out what in the world might be going on with me and I seriously don't know how much more of this I can take before absolutely going batty.
