Hope someone can help me. I am 54 years old and had right knee total replacement on Feb. 29, 2016. Woke up with pain in my neck and back with bad headaches. Was laid up in hospital for 3 days until pain went away. Since my stay at hospital I had no therapy due to having the pain and was always throwing up. When I was at home the pain in my neck and back came back, so did the nausea. After almost 10 days of this I found out it was because of the Spinal anesthetic. I felt better and did not have to do the procedure of injecting blood in my spine. For the next few weeks I had to do my own therapy due to not having approval from workers comp. for physical therapy. By the end of March first week of April my doctor suggested a manipulation. Of course I had to wait again for the approval. Finally approved, the manipulation took place April 28th. I woke up with excruciating knee pain as expected. I was able to bend my knee at least 60 degrees on my own. Again, I was still waiting for the approval for therapy. I finally got approved almost 3 weeks after the manipulation. I'm doing my best that I can with the help of therapist. On my second appt. the therapist was able to get me bended about 75 degrees. But to my dismay I can't do it by myself. It seems to get tighter. Therapist telling me I'm doing a good job, but I believe I'm stuck again and can't get further than 75 degrees. I don't know what to do but exercise the best i can. Can someone please help and advice me? I'm in constant pain.
