Hi Alkymst, yeah sorry to read you are suffering so much mate, just a couple of thoughts that come to mind, i noticed that just a little stress can aggravate the heck out of PN & nerve's repairing isn't that flash either and can go on for some time too, also i found that i built up some tolerance for pain meds after some time and i was thinking the PN was getting worse but when i backed off the drug for a little while and then went back on the original strength, it worked much better, or perhaps your doc can adjust your meds to be more suitable for your current situation, i hope it settles down for you soon.
