Do not recognize this acronym. I also lost muscle use and had much "fire" in my knees. I had a chiropractor that put a "TENS" on my knees and it reduced the inflamation greatly. Fish oil for inflamation was one of the first things I tried. If you read here you will hear , excercise to tolerance, I ride a pedal bike (Aero-dyne) almost daily until my legs say no more. I also had pain from lumbar to knees, plus PN symptoms. There was a period of muscle wasting that progressed in spite of physical and water therapy. The progression lasted about six months or so and leveled off. I am regaining strength slowly (think geologic slow). Everybody likes to tell their story so tell us what, if anything, happened and your symptoms, and what pain level, meds, etc. Fight against the panic, others have been there and are willing to help. Good luck, Ken in Texas.
