(((WW))) I don't follow the subject line with the paragraph... but I'm glad you are going to the pain clinic.
Let me forwarn you, they are going to say things that will make you mad as all get out, and make you want to turn around and go right back out the door. Please don't leave. Give it the good ole Harvard try! You need relief, and while the way they will go about helping you will seem like no help at all, you won't know unless you go through with it.
I hope you do gain good relief. Pain is the pits!
