I have not had sx as long, only 7 mo but MS so far is the only thing to match my what I have going on. I also have all negative tests, what can I say, I always did hate to fail a test.

lol
My symptoms include --
numbness, tingling (left sided)
weakness (left sided, arm, leg, face moving to left leg)
muscle tightness (mainly legs)
burning in legs (controlled by Neurontin)
tremors (come and go)
heavy arm (left, comes and goes)
muscle spasms
muscle twitching
cognitive issues (mainly memory)
speech issues (can't think of words, pauses between words)
2 distinct attacks (6 months apart)
symptoms greatly affected by heat
I've been to several different neurologist who have told me to look elsewhere. Last one told me either stroke or MS but not stroke and dx'x me with possible demyelinating disease. Have an appt with new neuro next month. I'm not ready to give up yet.
Hang in there and best of luck to you, Dawn
