I have a hard ropelike protusion on the back of my right knee when I stand and put weight.about 3 to 4 inches long..also a bakers cyst to the right of that...extremely hard to straighten knee after sitting, also a lot of pain in front of knee to the right of kneecap....Very hard to roll over in bed....Was sent by my PCP with exrays to an orthopedic surgeon....He said it was no injury just arthritis...He ordered blood tests, an arthritis medicine which I couldn t continue after just 4 days with stomach pain ; and physical therapy...It is so dibilitating, hard to believe it isn t something more than arthritis...Another thing I found strange was the orthopedic doctor didn t even examine my knee, or even feel the swelling..or do any range of motion...I haven t started physical therapy because I m afraid to cause more damage...
