Herniated discs often do not need to heal at all. That is because most minor and moderate herniated discs are not painful or problematic in any way. They merely exist. In fact, herniated discs are a common side effect of normal spinal aging.
Discs cushion the vertebrae, contribute to flexibility and help to protect the spinal cord. Discs are composed of a gel-like center (the nucleus pulposus) and a tough, fibrous outer layer (the annulus fibrosus). A herniated disc or bulging disc often is referred to colloquially as a slipped disc and a ruptured disc. No matter what you call them, these conditions can lead to nerve root irritation or impingement, which can cause traveling pain, numbness, tingling, muscle weakness and other disabling symptoms.
