@cit10jetjockey You are absolutely right. NO CURE AT ALL. I was diagnosed 5 years ago with PN, and my pain is gradually getting worse. Right now, for my pain is a buprenorphine 7.5 mg pain patch that I change every week (comes in a box with 4 patches). My pain doctor prescribed. Very expensive also. I had to have my insurer approval also. I'm now going to a high mg 10 mg. for the pain patch. Also have to have insurer approval before drug pharmacy will fill. The pain patch does help...takes the EDGE OFF so to speak. I'm quite use to hardly NO SLEEP. Now I'm having burning with my eyes. And, yes, PN can cause burning sensation in the eyes. I do keep close appmts with my eye doctor.
