hello and welcome to HCM,
The MRI report suggests a pathological process going on at the spinal level.
column is made up of vertebrae separated by inter-vertebral discs.
The inter-vertebral discs are catilages which act as shock
absorbers and allow friction-less movement.
The inter-vertebral discs between L4-L5 and L5-S1 vertebrae shows a protrusion and a bulge.
This process is called disc prolapse
It is commonly seen after back injury
Initially, it is managed conservatively by bed rest
and pain killers.
Most of patients recover with bed rest only.
I hope my answer is of help to you.
Kindly, post your feed back before closing query.
Thanks and take care.
