Wow you've really been through it. I did get a cortisone this morning in the muscle not the tendon so we'll see how that goes. He asked me if anyone else in my family had osteoarthritis. Yep, my mother. So are I have had a right hip replacement, two toes that were operated on for bone on bone. My left knee is bone on bone from a bad fall off a treadmill over 30 years ago but so far still doesn't hurt except pressure on walking up stairs or curbs and a cervical pinched nerve. At 84 I still walked a couple of miles but now between the torn tendon and the bursitis it's taking away the one thing that I really enjoy. Getting out in the air and walking. I've never been one for the gym. Also I have to try and stay away from a lot of germs as I also have CVID. Which means I don't have a complete working immune system. I look completely normal but my body doesn't fight virus or bacteria. I do weekly infusions of blood plasma of other people's antibodies. I also can't take anything stronger then acetaminophen because of GI issues. Are we having fun yet???
