Hello Thanks for writing to us According to MRI report your son has degenerative disc disease of lumbar spine. Degenerative changes occurs in spine due to aging and development of weakness in annulus fibrosis which allows herniation of disc. 1.At L5-S1 level there is posterior disc bulge with annular tear and large herniation of disc in left postero-central region.It is causing indentation of thecal sac and left neural foramen narrowing with compression of left exiting S1 nerve root. There is also straightening of lumbar curve most probably due to spasm. There is small early schmorl s nodes are noted at D10-11 to D12-L1 levels Treatment for degenerative lumbar disease includes physiotherapy or surgery. Effectiveness of both modalities are same.So,physiotherpay should be tried first. It causes strengthening of Para spinal muscles and it prevents further changes. Surgery should be the last option. There are also medicines like capsule pregabalin available for pain relief. Other pain relieving modalities are Ozone ablation,Radiofrequency ablation,percutaneous disectomy etc. Steroids are also used for foramen block,but it is not the definite treatment. Treatment can be planned after consultation with neurosurgeon. Get well soon. Take Care Dr.Indu Bhushan
