Moonchild, I don't want to be an amateur physcian, but... A few years ago, I had a "locked thumb." Woke up and it was locked down. I could pull it up, but it would click as I moved it. When I put it down again, it locked and I had no power to raise it. Turned out that a shot of cortisone cured the problem. I think you should see your doctor and quit guessing. You have too much at stake not to do so. Jim
