Is it possible for a herniated bulging disk to heal on its own without surgery?

Absolutely: In reality, over 80% of herniated discs improve without operation almost regardless of the treatment, whether medicines, physiotherapy, chiropractic, or just passage of time. The only time surgery is urgent is if there is neurologic deficit such as muscle weakness or loss of bowel or bladder control. People often have surgery if the pain is so intense they cannot take it any more.

Herniated disk: Most herniated discs heal on their own. Initial rest, physical therapy and anti inflammation medication all work to speed up the healing time. Surgery is reserved for discs that don't respond to the above interventions with continued uncontrollable pain or motor deficit.
