Dear patient Your mri report is suggestive of disc prolapse at two levels. Human spine contains vertebra and between two vertebra is intervertebral disc which is named according to the location of vertebra. So l45 disc is located between l4 and L5 vertebra and L5s1 is between L5 and s1. These two discs are located in bottom of spine. Now prolapse means this discs has come out of its space and compressing structures in spinal canal which includes nerves and the car. So your mri report is suggestive of disc prolapse at l45 and l5s1 levels with compression of thecal matter and nerve roots. For assessing severity of prolapse canal diameters are required which is lacking in your report. So considering your report you require conservative management. Avoid forward bending and weight lifting. Sleep on hard bed. Take tab diclofenac plus thiocolchicoside combination twice a day and tab ultracet one at bedtime. Start physiotherapy with 1. Back strengthening exercises 2 back extension excersise and 3. Abdominal strengthening excersise. Do this on regular basis and you will get long term relief. If you don t benefit by this then epidural kenocort injection is worthwhile. Hope this is helpful.
