Hi welcome and I am sorry for your suffering. This is a very warm and informative community. I have PN in my legs and they used to feel more weak then they do and the pain on top of that. Now I have the pain but from increasing what I do over the past 2 years they feel stronger so to speak. I am not saying for you to do this but just my experience. Also if your meds are not helping I would encourage you to call your doctor. There are many different ones that may help and some take a lot of time. Have you been to a pain doctor other then a internist? Hang in there and feel better
