22F herniated disc working out, will it heal itself?

I also have scoliosis (2nd photo). I was in the gym doing bicep curls with a straight bar and felt a pop with immediate pain following. I could barely get out of bed/ put socks on for the next week and a half. I have no pain now anymore but still wanted to get an mri and it says I have a small left central disc hernation at L1-L2. Will this heal on its own? What should I avoid doing?
