1.you’re not having muscle dz or nerve entrapment( but in july 2006 you might have entrapment, it can disappear with time) 2.you symptoms with hans and arms can be from cervical herniated disc. 3.thyroid won’t be so specific to your left side. 4.your twitching and numbness require checking electrolyte(+calcium and magnesium) level, thyroid function test, fasting plasma glucose .but the most important to think of is neurological dz, i’m not sure are you having seizures.but first , do disc operation which is frankly indicated.if the symptoms sustain, maybe brain imaging help esp in suspected epilepsy.but you can just wait, because sometimes it can regress in months or year if you have no new symptoms so.
