I had lower back pain for over 2 years. 7months ago I started running. Once every week for 1hour(~10km). First 3-4 runs I took pain killer, because I was ok during a run, but wasn't sure what will happen next day, then I stopped taking all pills and just went for 1-2hours run once a week. After a month or so the lower back pain was almost gone and I run more than 400km since. Of course, my whole body feels significantly better. edit: You should consult that you wanna start running/swimming with your doctor!
