Hi Electron, thanks for the response.
We are in the UK, so all's we can do is await an appointment from the Neurologist. Because of our location we don't have a resident neurologist at our local hospital.
I've started to question this myself. I'm wondering if the PN pain is masking another problem, more so as things are changing so quickly.
He is having difficulty walking to the bathroom and waits until his bladder is bursting, therefore any exercise is out of the question at the moment.
Since I posted the other day he is getting the very strong electric type shocks in his ankle and kneed joints too.
The pain meds aren't doing much at all

If he is not improved by tomorrow I think I will have to get the Dr back out and request he is taking into hospital.
Thanks
