Hi-My right TKR was September 14 and my major problem is sleeplessness. This is mostly due to burning hypersensitivity of the skin around and below the knee. I can’t stand the sheets touching the knee. Took 600 mg of ibuprofen and 2 Tylenol and actually slept 3 hours! Stopped Percocet which actually seemed to keep me awake.Sitting up icing it which helps but really would love a night of sleep. Trying to rub area with different textures cloth to “desensitize” the nerves as suggested by PT. Anyone else with this problem?
