<s>[INST] Iv been to several doctors about my back pain an they wouldnt explain the findings of my neck mri an I need help figuring what it means.they say that I have a posterocentral annular bulge of a disc which does not touch or efface the cord or existing nerve roots and then they say there is a 2mm posterior to the left disc protrusion resulting in narrowing of the anterior subarachnoid space.im very confused please help to explain this to me. [/INST] HiT hank you for asking ChatDoctorI have gone through your query. You MRI findings gives an impression of intervertebral disc herniation and associated spondylitic changes. But nerve roots or cord is not compressed. In such case I advise initially with muscle relaxants like cyclobenzaprine NSAIDs like Diclofenac and neurotrophic Chat Doctor. I also recommend doing physiotherapy along with this. Using a soft cervical collar also will be helpful. Hope this may help you. Let me know if you have any further query. </s>
