Hi Sunm...
My opinion...
You will probably get the ol' clinical examination/test- the walk on your heels, tuning fork thingy, etc.. and that will probably be it. Since you had an EMG already, most likely they won't do it again. Maybe, just maybe a MRI, but I'm thinking not. And then.... benign fasciculations due to stress.
How come it's so easy for us to accept an eye twitch as stress and lack of sleep but NOT one other body part is allowed to twitch due to stress?? I wish I knew that one. As an outsider looking in, you have dealt with a lot of stress over the last few years. Taking care of injured/sick people probably is not as easy as one thinks. I'm thinking your body is a little jealous and wants some attention, too. It is communicating with you- stop, breathe, listen and relax.
I wish you the best.
