Anatomy of the Sciatic Nerve

Someone you know may have complained about a condition known as sciatica, but what is it? To understand the condition, it’s helpful to know a bit about the anatomy of the sciatic nerve.

Sciatic Nerve

The sciatic nerve is the largest and longest nerve in the body. It begins at the base of the spinal cord and extends down the length of each leg to the toes on each foot. The sciatic nerve is really made up of five separate nerves that come together to form one large nerve that is as big around at one point as your thumb!

The sciatic nerves provide sensation and strength to the leg and connect the spinal cord with muscles in the thigh, lower leg, and feet. Muscle weakness or a tingling sensation in the legs can result when the sciatic nerve is compromised or compressed in some way.

An inflammation of the sciatic nerve or compression on the nerve can cause profound pain. This is the condition known as sciatica; symptoms of sciatica include a dull ache to moderate or even severe pain, shooting pains, numbness, or a tingling feeling in the legs. Individual symptoms and their severity can usually be traced back to where one of the five nerves originates in the lower back.

While treatment in the past may have included muscle relaxants, pain medicine and even surgery that had only a 60% success rate, chiropractic care has been shown to be quite effective in relieving the nerve interference and irritation that is causing the pain in the first place.

If you are experiencing any of these symptoms, and feel that sciatica may be the problem, please call our office to schedule an appointment. A thorough examination will determine whether or not you have sciatica and we can discuss what can be done to help.

Dr. Layn Asks some important questions of interest to Fountain Valley residents - Chiropractor Fountain Valley Dr. Layn Asks...

If you have a fever, are you sick or healthy?
Chiropractors love asking this question because it gets to the root of the chiropractic difference. Turns out fevers, vomiting, coughing and even sneezing are all healthy responses. It means your body is working correctly. Taking medications to suppress these natural processes can actually prolong your recovery.
What controls every cell, tissue and organ of your body?
DNA? Wrong. Immune system? Wrong? Hormones? Wrong. It's your nervous system, consisting of your brain, spinal cord and all the nerves of your body. When a chiropractor sees a Fountain Valley patient with say, stomach problems, we want to know why the brain is unable to properly control and regulate the stomach. Which prompts us to examine the nervous system—the focus of chiropractic care.
