You have started having pathological changes in your spine bones. The intervertebral disc is bulging and it would give rise to prolapse if it continues .

You have to maintain your weight, in proper BMI, wear proper shoes, proper position while sitting, sleeping, working. Exercise to increase the strength of your back muscles.
If you can avoid surgery by Physiotherapy then it would be good for you.

Visit an orthopaedician for examination and assessing your problem based on your MRI and follow up for treatment. Taek care!
