At Orewa Chiropractic, we treat all types of pinched nerves such as Sciatica or Carpal Tunnel and other symptoms in the limbs.


Sciatica is a term used to report the symptoms felt in the leg such as numbness, pain, tingling, or weakness. Its medical term is a radiculopathy following the pathway of the sciatica nerve due to different underlying causes:

Disc Herniation or “Slipped Disc”: the soft inner gel is migrating backwards to the edge of the disc provoking a bulge or if it goes through, a herniation

Degenerative Disc Disease or Spondylosis: like any tissue in the body after 25, the disc degenerates being more dehydrated, changing its shape and function. It will therefore “pinch” the roots of the nerve.

Piriformis Syndrome: the sciatic nerve, the largest in the body, runs under the piriformis muscle or even through sometimes. In this case, a severe contracture of this muscle will irritate the nerve, leading to moderate symptoms in the leg.

Pregnancy: the extra weight and instability of the sacro-iliac joint, located in the pelvis and in regard of the sciatic nerve, may cause pressure on the spine and compression of the sciatic nerve.

Spinal Stenosis: the nerves coming from the brain travel in canals and spaces in the spine. Mostly due to some local degeneration creating spurs call osteophytes, the canal can narrow (stenosis) putting some pressure on the nerves in the lumbar spine. 

Isthmic Spondylolisthesis: the body of a vertebra slips over another and so the root of the nerve may be entrapped, provoking chronic pain in a leg or two.

Trauma: like any tissue of the body, the sciatic nerve may be injured during any type of accident including a fall or car crash. 

“The Wallet Syndrome”: this is not a familiar diagnosis but it occurs. It is common that men put their wallet in the back pocket of their trouser. This can lead to a sustain pressure on the sciatica nerve going underneath and so being compressed.

According to one of these causes, the resented symptoms will differ, depending on the location where the nerve or its root is pinched.
