hey bro---just got done with an mri for the same problem...mri came back negative... if the pain is about 4 inches above your waist, and maybe 3 inches or so to the left or right of your spine, it's probably your fecet...it's a very tiny joint... i screwed mine up and it causes my lower back to kill, so much that it's hard to stand or do cardio, have to wear a belt to even lift...been doing ultrasound and some other things.. if it sounds like that, email me at [email protected] and i'll go into what i do, took about 2 weeks to even get it back...
hope this helps
later bro
