From last 3 years i feel great problem with my back...i feel like my back is not fixed in pelvis properly... I cant sit like others on any chair...i cant sleep straight over my back. I feel as if my posture is changing day by day...feel spasm in complete back. Whenver i wear shoes with heels i feel pain in pelvis , lumbar and neck region....whenever i lift weight my shoulders pain and again feel like loosing my posture..there is a difference bwtween both shoulder blades. Cant keep my neck uprigh
