75% in 2-12 weeks
90% of disc herniations are treated without surgery.
Most get better within 12 weeks. This is why 12 weeks of non op care is recommended as most will get better or are improving during this time period. The next 15% take longer &10% are treated by surgery. There is a 5% recurrence rate with or without surgery of another disc or same disc herniating. Bulging discs are normal variants, not bad.
