Going on two years ago I somehow tweaked my back while moving furniture alone like a moron. Multiple doctor trips have yielded pain pills (no thanks), multiple stretch/exercise routines (didn't help), and a suggestion for physical therapy (no time to go). One MRI done which didn't find any damage. The pain is in my lower back around the waist area and extends down the backs of my legs, predominantly my left leg. I'm typically ok when walking or sitting, but it hurts when standing still. Sometimes when sitting and always after standing still for more than 10 minutes or so I will get the tingly limb falling asleep sensation in my legs, particularly my left leg. I also lack flexibility when bending at the waist. I'm tired of fighting it but every time I go to the doctor they basically tell me that there's nothing wrong. I'm 6'1" 215 lbs and while I could stand to lose 20 lbs I'm not in awful shape, and otherwise in excellent health.

Any suggestions for fighting this on my own? Potential next step with a doctor or specialist?
