I have idiopathic peripheral neuropathy and Central Pain Syndrome. I had a failed back surgery. They missed the disc L4-L5 and burned my spine. I was diagnosed with PN through nerve testing. It took a year to diagnose the CPS. This was 10 years ago. My calf pain is pretty much 24-7. I am a new member here. I am also a Member of the Central Pain Foundation FB group. You might check it out. Lots of info. I just want to say Thank You for this group. Hope you have a low pain day.
