I have juvenile arthritis in my knees, and a few weeks ago I went to the hospital to "get it fixed" for the fifth time. But it didn't work, and the pain in my knees has gotten worse and worse. I take pills for my arthritis along with pain medication, but it doesn't work. I can't walk, stand up from a chair or bend my legs. The pain goes from my knees and up my thighs. The doctors says that there is no swelling, and only small signs of action in my knees, so why does it hurt so bad?
