I haven't even had that or a nerve conduction test , and my muscles do not respond at all to rehab i.e. the joints just get worse because of the added strain caused by lack of response . It seems now also after a PT exam I have Hyper mobility Syndrome too . My feet are swollen constantly and purplish which I am trying to argue is possible PN - but my shrink / doc say otherwise its because I,m not weight bearing ( I am disabled ) though they think its because I have delusional disorder / belief of Ehlers Danlos( look up DSM 5 - long stry ) . This however can no longer be the case with evidence of hyper-mobility all over my body and the fact HSM .JSM is an underlying feature of EDS so I'm hoping it will discharge me from where they've had me locked up for 3 months. In meantime I'm tying to find any excuse I can to show I have pn so I can prove that they rehab they 're trying to force me to do would not only having no effect but also be dangerous to my HMS condition.
