Sounds like classic MS to me but I am no doctor. I am dealing with left sided weakness as well right now but mine is more of left jaw, swallowing, neck, arm and leg weakness. I am a 36 year old male. MS was mentioned and Lyme also. Don't be completely fooled by Lyme though, when people don't know what wrong anymore they always blame it on Lyme. I am from Lyme, CT so I am treating my condition with heavy antibiotics just o be safe but I think I also have something else.
Keep me posted on your progress will you please, would love to know what you turn up with.
I had sudden onset of left sided facial and head dysesthesia after experiencing a complicated migraine Aug. 29, 1985. I have lived with the itching and burning since.
Do some research on lyme disease. Sounds just like late stage neuro lyme.
