Great. As some PT's will say on this website, nothing beats seeing a patient. Then the assessment is easier and we could change things as we work through things together.
I don't think that you've wasted anyone's time as discussions like this also allow us to help persons like yourself when it's an easy diagnosis and send you on to further help when it isn't as easy to distinguish.
We also get to review the literature when treatments may not be working, encouraging some PT's to do some more research in uncommon conditions.
I would have to agree with your PT so far, as your symptoms do sound as if they could be referred from a more central source (neural) and I hope that you progress well.
Do keep us up to date on how it goes?
