I also have had an operation on L3-L4 &L4-L5 and have lived with this bad back,and neck and now also thoracic spine for over 8 years. I am convinced that the pain from Pn and and burning that comes from a bad back are as different as day and night.

A bad back will cause sciatica,burning,aching,and even numbness. But I don't think it will cause itching,prickling,pulsating nor the vibrations that we have with PN.

When I do my stretches,as I stretch I actually get itchy prickly feet. That's the nerves being stretched and stimulated. I have a galley kitchen which is basically all lower cabinets. So I have to squat down to get things. By squating I mean I am sitting on my own legs and balancing my weight on me feet,as me feet stretch they start to prickle and burn. That is definately my PN and not me back.

At my very very worst, which was back in 2001, my back hurt so badly that my body actually looked deformed. I was twisted and pulled and mangled up,and I never had these "parasthesis".

If you are lying down resting comfortably, do you have any parasthesis?
