... was diagnosed with Osteoarthritis. I had a cortizone shot that did not work and then a series of Supartz injections in December. If anything the injections made my knee worse. The pain keeps me from sleeping and I'm reduced to walking with a cane now. I'm not sure what my next step is. I'm going to change my doctor as he doesn't appear to care to try or do anything to get this resolved. Any suggestions would be appreciated
