Question: Hello,
I woke up last night at 5:30am with both arms numb but after moving them, the problem went away in about 1-2mins. I also had an icy cold sensation in the central chest area, which seemed to go outwards. I have had the numb arms before during sleep and disturbing the sleep but usually only in one arm and it resolved after movement of the arm. Could this be something neurological is it perhaps something to do with the heart, a weak heart or blockages preventing total blood flow to the extremities?
I should mention that I am currently awaiting neurological evaluation for leg muscle fasciculations which are ongoing with various levels of intensity and these may be related to the sensation of pins and needles which I am also experiencing after the onset of the muscle twitching, trembling and shaking.

Hi,
Thanks for the information and assurance.
I presume that there is likely no connection between the twitching and the temporary numbness during sleep.
By overt nerve compression, do you mean something in the central nervous system whereas minor nerves are those in the arms and legs?

Thanks.

Hi,

Thanks again. I have asked about my muscle twitching online before, would you agree that emg, nerve conduction, blood tests and possibly mri of brain/spine are possible tests to rule out serious disorders? Is it important who does the testing to ensure the emgs are interpreted correctly or is it quite straightforward issue?
What about muscle biopsies, have they ever been used to diagnose diseases associated with muscle twitching?
I do not want to go overboard with testing but at the same time don't want to miss anything serious which might be treatable.

Thankyou.
