Second Surgery

I have pvns and was diagnosed back in 2007, I have had one authorscopy surgery and am have open surgery in 8 days. I have had problems with my knees since I was a little kid, I remember my parents having to rub my legs through the nught cause of the pain, the doctors said they were growing pains. As I got older they said I had a number of differnt things intill I had my first surgery and a biopsy was done. Now I am in so much pain, that comes and goes, moves from the knee down to my ankle and up to my hip. I also am having pain in my lower back due to the pvns. Iam praying that this surgey relives most of my pain.
