Truth be told mate. Chances are that the pins and needles were just a byproduct of sleeping position. The pins and needles you get in vcjd comes and stays put. It doesn't fade away. Just a weird coincidence or maybe due to the insomnia/anxiety affect my sleep position rather than a direct result of brain sponging.
The burning legs upon touch, cold feet and eye sensation is most definitely constant though and point right in the scary direction.
