I had my MRI done for Dorsolumbar spine and the result was -diffuse disc bulge at L4/5 level indenting the thecal sac with bilateral foraminal encroachment - mild posterior disc bulges at L3/4 and L5/S1 levels. I wanted to know if my problem is severe or not

Hello and welcome to HCM,
The interpretation of the MRI report is as follows:
There is bulging of intervertebral discs at different levels of the spinal cord.
One of bulge is at level of L4-L5 and this is a diffuse bulge.
Other bulges are at levels L3-L4 and L5-S1. These bulges are present posteriorly.
Intervertebral discs are cushion like structures present between vertebrae.
Bulge of these discs can further cause prolapse of the discs and compress upon the nerve roots emanating from the spinal cord.
Thus, management of this condition is required.
Bed rest is sufficient to reduce the bulging intervertebral discs.

Thanks and take care
