Recently I took a bit of time(4 months or so) off from exercising. Yesterday, I tried to go do a little running at the local track to see where I was at, and after my first warmup lap, I tried another lap and about 2/3 of the way through it I noticed the muscles in my lower back began to hurt, and the more I ran, the more they started to hurt. I wasn't that winded or anything, just the muscles in my back hurt. So I decided to try to walk half a lap, run half. I did that for a total of 1 lap because by then my back began to hurt so bad I almost couldnt bear it. So, I tried walking a lap to see if it went away, no go. I got my stuff, went to the car and when I sat down in the car seat it started subsiding.

I have no idea what could be causing this, as I have a very strong back(I'm a former powerlifter, and deadlifts were my favorite exercise when I was going to the gym). Any information would be greatly appreciated.
