I have both a protrusion (bulging disc) and an extrusion (ruptured disc). After two hours with the neurologist my understanding is that the extruded disc needs to be “metabolized” - it needs to go away. Exercise and healthy lifestyle helps with that. Doctor also mentioned enzyme supplements, though she said it was her opinion. As for the herniated one - exercise, taking care of your back (“healthier” sitting, changing positions, correct sleeping position etc…). Surgery should be considered as a last resort (they might have to break part of the vertebrae to get to the disc). To surprise of nobody, these recommendations help me feel better.
