Hello, thank you for your question.
MRI report of ~90% of population will show mild to moderate disc bulges at one or more level which are asymptomatic. So, first thing to keep in mind is that all discs are not worrysome.
Disc bulges do not heal. You can only decrease the compression on your nerve due to disc bulge. For this, various modalities are used by orthopaedic surgeons.
With proper care and treatment, you can definitely lift weights in future.
