Welcome to Health care magic. 1.The disc is located between the vertebral bodies, serves as a shock-absorber effect for weight bearing and body movements. The disc contains a maximum amount of water % with in. 2.When these disc due to age related degenerative changes and excessive usage ( hard working with weight lifting job) gives loss of the water percentage is called dehydration, which is classified in to mild,moderate,severe. In your case its moderate. 3.When that happens the disc slips / herniates and causes pressure effect on the nerve and spinal chord, which is happened in you at multiple levels ( with this symptoms are seen) 4.GEnerally physiotherapy will be used initially - if docent works then operative procedure / interventional procedure is used as treatment. 5.Interventional is better i can suggest if you have tried rest all as its less invasive than the operative. Good luck. Hope it helps you. Wish you a good health. Anything to ask ? do not hesitate. Thank you.
