Question
so I have this problem with my lower back that has been coming back for some months now. Well it started with pain in my lower back mostly on the left side it didn't really hurt sitting down but when I ran (oh by the way i play soccer) and accelerated and then started slowing down the pain was really bad and it sometimes went up my back the more I played. I went to the doctor and they said it was a ligament inflammation and told me to rest but the pain continued. I currently have the pain right know and like i said i have been having this problem off and on every three weeks or so. My left knee has also been swelling up could that be the problem from my back? The main thing what is it and how can i cure it? Thanks.

Answer
The knee issue can be from the back...it sounds as if there is mechanical locking in the lower spine, leading to inflammation.  A good chiropractor should be able to get the inflammation down, correct the problem, and set up a rehab program to re strengthen.
