I'll let those of you to whom this may apply internet search engine it for yourself and just consider if it might be applicable to your situation - it's just a thought to consider for me and for you. I've taken steps to reduce this occurrence in my leisure time - we'll see what the new neuro thinks.
Ok, as I stated in earlier posts, my local neurologist is stumped (which is common with PN) as to the cause of my PN. I have an appointment in June with a specialist neuro at a large regional hospital.
One of my last Qs or ideas on what may have caused - be causing my PN just occurred to me: Though I am blessed with the ability to be - and am still - very active, I often sit in a reclining couch with my feet up for prolonged periods - 2 to 3 hrs. Coincidentally ? about the same time I started doing so (five years ago), my initial PN symptom presented onset. When I sit during these periods, I cross my legs with one knee consistently resting against the back (calf) of the upper leg - thus creating pressure on the calf and consequently on the tibial nerve which runs through that area to the lower leg / foot. On more than one occasion, my upper leg - which has my lower knee jabbing into its calf - has been somewhat numb from the knee down when I finally arose or uncrossed my legs. SOOOOOO - I search engined "pressure on tibial nerve" and found that in an article or two "Tibial Nerve Dysfunction" can be caused by many factors, including pressure on the tibial nerve. I didn't discern how much pressure and for how long, as I waned to get on here and at least throw it out there b4 I forgot about you guys. The key point was that the articles said damage or pressure can present PN symptoms in the feet and lower legs.
So, if you're yet to be diagnosed as to cause / origin of your PN, consider if you have had any event which could have resulted in pressure or damage to your tibial nerve - at any place it runs throughout your lower leg - or if there could be a narrowing of the nerve canal through which it runs.
Like I said, it's a shot in the dark, but something else for you and your doc to consider. Good luck. I'll let you know what my new neuro thinks and if he performs any test to check the tibial nerve function. Rory
