MRI report is suggesting about disc bulge severity of which is assessed both clinically ( like you have back pain but not going to the legs ) and from MRI image(not available) .
So currently good thing is you have only back pain so take 2 weeks of Rest( not doing exercises)
Next Steps
start Tab Zerodol SP BD for 7 days with
Tab Razo D empty stomach for 7 days( check for any allergy)
start USD/TENS from nearby physio centre for 1 week that will help quickly.
After 2 weeks when you start feeling better with no back pain, start back strengthening exercises regularly to avoid future disc problems.
Health Tips
avoid forward bending, weight lifting or exercises for at least 2 weeks.
