I can understand why you might start to think your doctor is blowing you off. I thought his conclusion that your twitches were benign without the benefit of an EMG was a little odd....or is it just me?
Now if he thought it might be a virus (seems logical, I've learned enough here and elsewhere to know that something like that can bring these symptoms on) why would you think spinal tap? Is that because if something like this was virus related it would be in the spinal fluid? I didn't know that...
Are you getting any other blood work done? After my first exam, I had EVERY test on the blood work sheet.
I think you should take some comfort in the unremarkable exam, as easy as that is for me to say! March 4th will be here before you know it.
