i have extreme pain in my hips when i try to walk.. i can only walk about 2 city blocks before i get a shooting pain in my left or right hip, along with my left leg shooting needles all the way down my leg, then it will not support me for the next steps,, i have seen the VA for the past 4 years, had upper thoracic and lower lumbar injections, and a bunch of mri cat, and x-ray,, but no one seems to be able to find out why or relieve my pain.. what am i suppose to do?
