[|Human|] I have been active person in my life and now 87. I have gained about 15 pounds. I suffer from low back pain and it has worsened since a I had another knee replacement last year. The old one was 21 years and was put in in 1992. It still hurts and with my back painful for sitting, I wonder what can be done to be more comfortable? I take strong pain pills and exercise twice a week with a group. I also have stretch and other ways of trying to rid of pain. What do you think of the back injections? I do try to keep going and see and do many things, but I am also a writer and an artist. This means sitting much. I believe waiting to see a good specialist makes it worse. Why is Canada so terrible for waiting for a specialist?
