Give It Time to Heal on Its Own. WebMD's treatment overview estimates that 50% of patients heal within the first month of herniating a disc as the inflammation decreases. Within six months, all but 10% of patients heal, and it is these 10% of patients (like my son) that opt for surgery for their herniated disc.
