Hello, thanks for the details of your MRI.
There are degenerative or age-related/wear-and-tear changes in the lower aspect of the lumbo-sacral spine (lower back), mainly involving -
1. Facets- these are the small intervertebral joints- involvement is similar to arthritis.
2. Disc- Parts of it bulge/herniated out, with Mild pressure on the spinal cord canal sac, which is located posteriorly.

There is no compression/stenosis of the areas where the spinal nerve roots pass i.e. neuro-foramen, nor is there significant stenosis/pressure on the central cord canal- both of which can give rise to pain.

To summarize, your MRI shows mild degeneration of lower part of spine.
It is important to correlate the report with a history of your symptoms and a physical examination.
Hope this is helpful.
Take care.

Hello.
Thankyou for contacting HCM.

I have gone through your MRI report and will try my best to simplify it for you. Thecal sacs are basically where spinal canal is present from which nerves emerge which pass out of neural foramina to supply various parts of the body.
When there is narrowing of the thecal sac there is pressure on the spinal cord. Concern arises when this is narrowing significant to the point of presenting as numbness/ loss or altered sensation of limbs or loss of motor function. In that case one needs to consult a neurophysician. Your report has mild degenerative changes which happen with age or minor trauma. For this I would recommend consulting a physiotherapist for advice accordingly.

I hope this answers your query. Please feel free to contact HCM again if you have any concerns.
Wishing you good health.
