I am not dx'd with anything yet. My neuro says I show signs of both a CNS and PNS disorder. I'm just wondering if those with PN can have nearly normal neuro exams.

I have a mildly positive Rhomberg, brisk reflexes in lower extremities and reduced in upper, reduced sensation with the pin prick testing, I cannot stand from a kneeling position. And, after kneeling I have severe muscle pain.

Anyway, I just wonder if I had more abnormalities on exam if more testing might be done. I keep having repeated MRI's, but not much else. I had an EMG and nerve conduction testing done a few years ago (for the second time), but this has never been repeated. I've been reading about the skin biopsy and I wonder if this might help lead me to a dx. Although I have a good relationship with my neuro, I am hesitant to bring it up. I've been burned by so many neuros and I don't want go there again. Yet I know something is wrong and I need to advocate for myself. Any suggestions on how to handle this?

Thanks for any help.
