Yes, spinal discs can hurt, but not always directly.
Here's a more detailed explanation:
-
Discs Themselves: Healthy spinal discs don't usually have many nerve endings, so they don't typically cause pain directly unless there's significant damage or inflammation.
-
Disc Degeneration and Pain: As you age, spinal discs can degenerate (break down). This process can lead to problems that cause pain.
-
Bulging or Herniated Discs: If the soft, gel-like center of a disc (the nucleus pulposus) pushes through the outer layer (the annulus fibrosus), it can bulge or herniate.
-
Nerve Compression: A bulging or herniated disc can press on nearby spinal nerves. This nerve compression is a common cause of back pain, as well as pain, numbness, or weakness in the legs or arms (sciatica).
-
Pain Resolution: It's important to note that in many cases, the pain associated with a bulging or herniated disc resolves on its own without the need for surgery or extensive treatment. The body can often reabsorb the bulging disc material over time.
-
Other Sources of Pain: Back pain can also originate from other structures in the spine, such as muscles, ligaments, and joints.
In summary, while the disc itself may not always be the direct source of pain, problems with spinal discs, such as herniation and subsequent nerve compression, are a frequent cause of back pain and related symptoms.
