Your MRI report doesn't show anything that needs to be addressed urgently.
Many times back pain can be addressed by exercises alone. So look into your fitness.
Next Steps
1. look at body weight- if your BMI is high consider reducing weight
2. smoking- if you smoke, you need to stop. it's bad for your back.
3. exercise- do strengthening exercises for back and abdomen and core strengthening.
Health Tips
any medication for your back pain is likely only symptomatic treatment and doesn't change anything.
