Hey, thanks for all the comments
My hubby went back to the GP that diagnosed PN, yesterday evening. He was very apologetic and removed the diagnosis from the records (for now) - this is not to say he doesnt think my has PN, but without further tests etc and the GP not being in the neuro field, he has decided he was wrong to diagnose at this stage.
Hubby has asked for whatever tests need to be done to rule PN in or out and is now awaiting for a scan on his neck

and also awaiting an appointment with specialist. GP has suggested that hubby may have a cyst in his neck that is causing the problem in his hands - this is related to a lump my hubby has in his lower back next to his spine (which he is now told could also be a cyst that is causing the problem in his feet) He had blood work done for the lump in his back, back in March which came back normal as far as growths are concerned
We have done, what I presume is only alittle research on PN and currently, cannot find out a primary cause if he does have PN, hopefully with the help of a specialist, we will find out more, but will continue to research further ourselves.
Thanks again for the responses
