Herniated disc
A herniated disc is one of the most common causes of back pain — and, in most cases, it improves without surgery, with the right treatment.
Between one vertebra and the next there is a disc that works as a shock absorber. When part of it shifts and presses on or irritates a nerve root, pain appears — it may stay in the spine or radiate to the arm or leg.
Having a herniation on a scan is not the same as having a symptomatic herniation: many people have changes on imaging and no pain at all. That is why the scan is always read together with your history and the physical examination.
Most herniated discs improve with conservative (non-surgical) treatment: pain and inflammation control, specialized physical therapy and movement re-education. Injections and orthobiologics are added depending on the case.
Severe pain that does not improve, progressive loss of strength or significant neurological signs. In these cases, endoscopic (minimally invasive) spine surgery treats the herniation through a small incision, with less pain and a faster recovery.
