Degenerative Arthritis

So I went to the doctors today (Once again. So sad when you walk in the dr's office & you don't even need to tell them your name) & he had my results back from my CT Scan, he said that it shows I have a early onset of Degenerative arthritis in my TM joint. Just lovely. So obviously that means this pain isn't going to stop. I'm scared how much worse this pain is going to get, its already bad enough. I'm scared.
