Pain In lower back

The pain in my lower back is back AGAIN!!! It comes and goes, but mostly it's been a nagging pain for the past 2 weeks or so now. Is my UTI back again? Did it ever really go away? I'm not sure. This pain comes a goes, and seems to get worse when I'm wound up and stressed. So for the next three days I will relax and probably wreck a few more bottles of Pink Truck. Which will be LOVELY!!!!!!!!
