Pain 2 Inches Above Butt on Spine

Hey guys,

I have been having pain on my spine 2-3 inches above my butt crack. When I press on the spot on my spine with the pain, it feels like it is bruised.

I still can do my normal activities, I deadlift and squat without any pain. I stretch as often as i can. The only time the pain is triggered is when I am trying to stretch out my hamstrings (bending over). This has been going on for about 2 months.

Any ideas on what it could be. It is only mild discomfort.
