Cass, hate to hear you're in so much pain. I know its tough but you will beat it. I know you didn't ask for any advice but I have to. You blame it on aging. And i'm not totally disagreeing with you. But I think a lot of us forget the number one thing that helps prevent these things from happening. That is exercising. The older we get the more important for us to do it. And I only like to remind everybody how important it is for us.
