I had a back pain a week ago and give it a 4 days rest. After the 4 days, I start to play tennis again. I feel some numbness in my leg, but thought that it from a 4 days rest. A few days later after a good tennis day, my leg begin to go from numb to pain. The pain is from my right buttock to the back of my right knee. I had a back surgery before due to same symtom and knew what it was right away when the pain began. The pain is there, but it's not that bad. I can still walk, sit, and sleep, but quite nervous about playing tennis. I'm affraid that (playing tennis or not) will cause another surgery - something I cannot afford right now during this tough economic time. Can this pain goes away without surgery? If so, what I can I do? Please give me some advise.
