Avoid forward bending. In this case a good physiotherapist can help you better than medications. & Most important thing if MRI report says disc is prolapsed or annular fibers tear etc then pls take advice of orthopedic surgen.The cause of Your pain in winter seasons are stiffness and spasm which leads to reduce mobility of joint.
