I did have an injury to my lower spine when I was about 18, but these problems didn't start until around 55. I have been seeing a chiropractor for almost a year - x-rays every 3 months - I just gave up on the neurologist after 5 years and no answers: but the chiropractic hasn't touched the PN. It's worse. No MRI has been done - but I've seen 4 neurologists had three nerve conduction studies and whatever the procedure is that tests your muscles. It's in my hands and feet. Both hands have had carpal tunnel release surgery with no impact on the neuropathy.
