Sciatica can cause serious and persistent nerve pain that originates in the spine and typically extends down the back of the leg. For many people, the pain from sciatica can be excruciating and debilitating, sometimes making standing or sitting difficult or impossible.
The sciatic nerve is actually a bundle of five nerves that exit from the lumbar spine and sacral foramen. These nerves group together at the piriformis muscle in the buttocks to form the one large sciatic nerve, which then travels down the back of each leg. The sciatic nerve provides strength and sensation to the legs and connects major muscles with the spinal cord. A problem with the sciatic nerve can cause muscle weakness, numbness, and pain.
Often misunderstood, sciatica is not the cause of the irritation at the nerve root, rather it is a set of symptoms. Some of the conditions that cause sciatic pain are:
- Herniated or slipped disc (most common)
- Piriformis syndrome (muscle in buttocks becomes tight or spasms)
- Spinal stenosis (narrowing of the spinal canal creates pressure on the nerves)
- Spondylolisthesis (slippage of a vertebra, narrowing the nerve exit)
- General wear and tear on the lower spine
As the body ages, risk increases for sciatic nerve issues due to age-related changes in the spine, such as herniated discs and bone spurs. Obesity also can increase risk, as excess weight can contribute to spinal changes. Diabetes increases the risk of nerve damage and is another risk factor for sciatica. Other lifestyle factors such as occupation and prolonged sitting can play a role in the development of sciatica.
Chiropractic care and adjustments are a viable option for treating the pain and symptoms associated with sciatic nerve issues. A 2006 study published in Spine found that manipulations (adjustments) helped relieve pain due to acute back pain and sciatica. Another study published in 2010 found that sixty percent of sciatica patients (who hadn’t found relief from other therapies) experienced the same level of relief from chiropractic adjustments as patients who eventually had surgery.
