Thanks for your responses. it's so nice to hear from people who are experiencing similar symptoms to me. I am definitely going to get a second opinion if I reach a dead end tomorrow.
As for the heaviness, I am experiencing that with my legs and arms. With my fingers, occasionally I can't let go of objects. When I go to spread my fingers out 2 of them always seem to stick together and wont separate. That happens all the time.
I was given the ice test and my eyes improved dramatically. I've noticed that I can't sustain an upward gaze as my eyes flutter and close within seconds, however this doesn't happen after I apply ice to my eyelids.
The spasms that I experienced earlier on have not returned. I can feel and see muscles twitching occasionally but they're slight and don't last for more than a few seconds at a time.
