Will Lyrica Help Subside The Numbness In Leg With No Possible Diagnosis?

Hi-I am a46 yr old lady -very busy lifestyle, tall and thin working ax an X-Ray technologist for 24yrs. Painful symptoms began in my left buttock region last fall. By Xmas started having numbness down my left leg-quickly progressed bilaterally. Was unable to sit hardly at all over Xmas. Had emg test which showed s1radiculopathy. No definative disk bulging on MRI. No sacrilitis-Ddd-and some facet arthropathy . On lyrica for pain now-no real relief yet-can t ride in car for very long-very debilitating. Need some help to get back to work and life? Physio for fore strengthening isn t doing anything. I live in ontario near Guelph and waterloo-do u know anywhere I ould go for help? Or who to see?
