Your best bet is to find a good chiropractor, preferably one that specializes in sports injury. I agree with netman about the miracle cure, but with a good chiro, a little bit of muscle strengthening to prevent future injury, and a training regimine (number of times of tennis per week and work out time) that works for you can greatly reduce your problems.
The great part about a chiropractor is they will work to fix the problem, not just cover up the symptoms with NSAIDs, however please remember that fixing spine problems requires work on the part of the patient as well as the doctor (healing time is greatly accelerated with a cooperative patient).
If you are having a problem finding a qualified chiropractor, try this website

(this school is respected world-wide for the higher than required training given to their doctors).
Good luck and feel free to email if you need any more help.
