Spasming and negative test results.

[Flower_Girl23]

Hello.
My husband has been having muscle spasms (mostly on the left side, mostly on his arm) and twitching for about 6 months now.  They admitted him to the hospital once and found nothing.  They ran MRIs, CAT scans, EKG, and other tests.  They ran blood test for the electrolytes and vitamins, blood sugar, thyroid levels, lyme disease, and Huntingtons' disease.  They have all come back negative.  The doctors have no idea what is causing him to spasm the one minute, and paralyzed in the next.  Some days are worse than others.
We are seeing a chiropractor Monday, as I was suspected that maybe he has a pitched nerve somewhere.  They did an EMG of his left arm yesterday, and it came back normal.  He works extensively with computers and heavy lifting for work.
Is there anything else that I'm missing?  Anything else I should do?
His symptoms include (note: these could be unrelated):
  Weakness on his left arm
  Muscle spasms, especially abdomen
  twitching on his left hand
  temporary paralysis of his whole body (usually up to 2 minutes)
  low temperature (96.6 as of now)
  stomach aches
  hoarse voice
  sore throat
  Poor balance
  Lost of thirst
  weight loss

Any info, no matter how small, would be appreciated.  Thanks!

A hoarse voice is not just in a person's head, unless it is somehow faked.  I am glad he's gotten some help for his shoulder.

As far as I know, they did the echocardiogram while in the hospital, came back normal.  They also did MRIs of the brain and spinal cord with nothing unusual noted.  Most doctors now look at him and his prescription list and, since he is diagnosed with Bi-Polar, tell me it is all in his head.
Yesterday we went to see a chiropractor as his left shoulder has been bothering him for over a year.  After the first visit, he could stand without spasming, wide awake.  I'm starting to think that it was some highly irritated nerve that was causing this somehow, though I'm not sure how.  At any rate, he is doing much better now than before, and we hope he can work the entire week this coming week.  Hope it all goes well.

In all their testing, did they do an echocardiogram, carotid ultrasound, check for an abdominal aneurysm, refer to ENT (or head & neck) for poor balance (see if it's vestibular related), sore throat and hoarse voice?  Did they do a brain MRI, including a special attention on the pituitary and hypothalamus areas, with and without contrast?
