Intervertebral disc space is reduced - may be any reason: Arthralgia, arthritis, degeneration of joints; may be osteophytes etc Physiotherapy and muscle relaxing and neurotonics medicines are advise. Herbals are more sustainable and effective, though slower in action. If you can get Harsingar plant leaves, decoction of it may drunk for few days to get much relief. Vaatnashak herbal medicines such as Rumalya forte, mahayograj guggul etc are of use. Mild Yoga postures, deep breathing also helps. This problem doesn t go easily. Popping antiinflammatory and pain killing drugs often is no solution. Post hot water bath, Mahanarayan oil may be applied over back as gentle massage, turmeric in warm water / milk may be drunk daily or take Haridra capsules. Had I rec d ESR blood report, uric acid report, ultrasonography or x Ray of spine, I would have been fully equipped to answer more details. Hope it helps.
