I would recommend you to repeat your MRI as previous one was 3 years ago. If it shows that disc prolapse
has progressed and it is compressing nerves now i would recommend you to think about surgery. Apart from that there is role of physiotherapy
., Physiotherapy helps by strengthening muscles and ultrasono provide relief from back muscle spasm. If it is increasing pain in you then i can recommend you other modes like epidural steroids
and infrared and TENS
. But remember that disc pain takes time in healing.
