Hang in there Peter. I'm pulling for ya. I supposed to get the Left TKR last July. That didn't happen, they wanted to do an MRI which told them once again I needed it. Such a hassle working with the VA. They gave me a cortisone shot that lasted a week. Went back down a month ago for a follow up and told them get it done. So I have a TKR scheduled for next year sometime. They are also going to give those gel injections in the near future as well. Lot of pain as you have already experienced. Doc Say's the TKR may or may not elevate all the pain I feel. I don't get it.
