Hi Liman - never been through anything like that before. The back was so stiff/painful that I could barely walk. Turned into a real SOB for a good while there. Didn't have any trouble with the knee replacement a couple of years ago, then a sore back knocks me down for a couple of weeks??? The MD couldn't figure anything out and tried to give me percocet, but I told him to keep it & ended up just using tylenol/motrin. Chiro got sick of seeing me all the time, but finally got things feeling better. I felt bad about missing you, but was really hung up for a couple of weeks there, barely able to get into work. Haven't played in months, and it's (both the back and the lack of play) not bothering me a bit!
