I had tkr January 30. I have tried everything for pain, mostly they didn’t seem to help. Percocet, Vicodin, Voltaran and Tylenol. I could not sleep at night that’s the worse part of healing. You need your sleep! Finally I visited my primary care doctor and she said to try Neurotin. This has worked for me I take this with Tylenol and Voltaren every night. Most nights I can sleep. I am getting better but it’s a process. Hang in there! God Bless
