HI, thanks for using healthcare magic
Between the vertebra (the bones in the back), there are discs. These discs are made up of an outer ring called the annulus
fibrosis and an inner part called the
nucleus pulposus.
The bulge that was seen between L5 vertebra and S1 vertebra was a bulging of the outside ring or annulus.
The theca is a sheath covering the
spinal cord, due to the bulging of the annulus, there is also is distortion of this sheath.
The imaging also saw bulging between L3 and L4 vertebra and L4 and L5 vertebra.
The
bulging disc is compressing the
nerve that is exiting from the S1 vertebra or bone at the level of S1.
These results would definitely contribute to your pain. Your doctor would likely suggest referral to the physiotherapist.
The physiotherapist would be able to demonstrate exercises that may help you.
You may also need medication to help reduce your symptoms.
It can sometimes take a months,sometimes up to a year for improvements to be seen.
I hope this helps
