How Nerves work!
Nerves are like electrical cords that carry information from the brain to the rest of the body and vice-versa. They are distributed throughout the entire body.
Motor (efferent) nerves carry information from the brain out to the body. This allows the brain to send commands to the various organs of the body. For example, these commands are sent to the muscles causing them to contract and move, or sends information to the heart to either beat faster or slower.
Sensory (afferent) nerves send information from the body back to the brain for processing, including information about pain, touch, taste, temperature or other information.
The information travels along the nerve by an electrochemical signal, much like information traveling along an electrical cord. When a nerve is pinched, the signal is interrupted somewhere along its path.
What causes a Pinched Nerve
A pinched nerve is caused when a nerve is somehow damaged or injured by direct pressure or compression and is unable to properly conduct its signal. There are many potential causes for a pinched nerve, depending on the location of the nerve. This cause can be examined and the problem can be diagnosed.
A pinched nerve in the neck or lower back can be caused by a vertebral joint restrictions, muscle adhesions/scar tissue, herniated disc, arthritis, bone spurs or spinal stenosis. These can be due to an old accident, improper sleeping positions, and posture at your desk, to name a few!
When the nerve is pinched due to one of these issues many different problems or symptoms can result!
Spinal stenosis is a narrowing of the spinal canal through which the nerves pass with the spine. A pinched nerve in the lower back or buttock can compress the sciatic nerve, which can cause sciatica.
How is a Pinched Nerve Diagnosed?

Dr. Barbara Rodwin will ask various questions about their pain, numbness, tingling, weakness, and other symptoms. The patient will be asked about other medical conditions, work history, and family medical history. This information can often assist in identifying the nerve(s) affected. Dr. Rodwin will then examine the part of the body involved. This will include testing the patient’s strength, sensation, and muscle tone in specific muscles. Depending on the results of the medical history and the physical examination, the patient may need additional tests.
If Dr. Barbara Rodwin suspects the patient has a pinched nerve (compression of the nerves) in the neck or lower back, X-rays may be necessary to assess possible injury to the spine or arthritis of the spine. Depending on the severity and duration of the patient’s symptoms, the patient may also need a MRI scan. Dr. Rodwin may also recommend specific tests for the affected nerve including a nerve conduction study or an electromyography (EMG).
Symptoms of a Pinched Nerve
The symptoms of a pinched nerve depend on what nerve is affected. Each nerve is responsible for sending information to or from specific parts of the body.
The most common symptoms of a pinched nerve are: pain, numbness, tingling (pins and needles), or weakness of the muscles along the path of the nerve, prickly sensation, stabbing sensation, burning sensation, pain radiating outward from the injured area, the pain may come after periods of sitting or standing, the pain maybe intensified while coughing, sneezing, and laughing. A weakness in the leg or foot is also a common symptom of Sciatica or a pinched nerve. Also your fingers, hand, toes, buttock, foot falls asleep and you have to shake it awake!
Carpal Tunnel Syndrome
A pinched nerve in the wrist from carpal tunnel syndrome typically affects the thumb, index, and middle fingers. It can also cause a weakness in the patient’s grip strength, and atrophy (muscle wasting) of the muscle of the palm near the thumb. A pinched nerve in the elbow from cubital tunnel syndrome affects the forearm, the ring (fourth finger), and the small fingers of the hand. Chiropractic adjustments, active release, massage and acupuncture are very effective for treatment.
As well changes to a workstation and a brace may be needed.
Treatment for Pinched Nerves
Any type of pinched nerve can be treated. Sometimes the treatment may involve surgery! This should be considered as the last result in the course of finding an answer. Surgery does not always solve the answer, as we see when patients come in to have treatment after surgery.
At Back to Health we like to try the conservative approach first for a pinched nerve. This will involve examining the area, determining the reason for the pinched nerve and offering our advice on ways to unpinch it.
We offer treatments such as: massage for the muscles, active release to the nerve and surrounding tissues, a nerve entrapment technique for the nerve, chiropractic for the surrounding joint that are normally involved, acupuncture for the nerve symptoms and aiding in healing the nerve, advice on proper mechanics for the nerve, stretching, strengthening programs to aid in strengthening the area.
Nerves can be tricky and often require more than one treatment approach, take awhile to heal and require management! There is not a cure for nerve issues that is quick and simple.
Why does my neck or lower back hurt? Could it be a pinched nerve?
Does your neck or lower back hurt? Did you do something funky, and now there’s pain?
You are not alone! Neck and back pain is in fact such a common problem in humans, studies suggest that over 90% of all adults will experience neck or back pain in their life time. Don’t panic, usually neck or lower back pain can be examined and treated! Even though there are temporary cures that bring relief to neck or lower back pain, if you want to secure yourself against future injuries, you need to learn about the REAL cause behind why your neck or lower back hurts & pinched nerves.
Let’s clear up any confusion you have about all of this stuff, so that you can get the proper treatment, and not have to suffer from pain any longer. Find out why your neck or lower back hurts and what pinched nerves have to do with it.
A pinched Nerve is a nerve that is trapped and has something pushing on it. That will cause pain to shoot down the length of the nerve, which is why sometimes you will have pain radiating into your leg or arm.
It can be caused from: abnormal sleeping positions, flat pillows, improper work station set-up, leaning forward in you chair, old injuries, accidents, repetitive motions that are not correct, hereditary factors, improper alignment of your body, vertebral joint misalignments, tight muscles, adhesions in the nerve and disc herniations.
Sciatica
Leg pain – often diagnosed as Sciatica –can be a painful and debilitating problem that commonly interferes with walking, standing, sitting, and sleeping. In some cases it is difficult to find any comfortable position at all. Along with pain, symptoms such as throbbing, numbness, weakness, and “pins-and-needles” can also be present. Adding to the frustration of these symptoms, this type of leg pain is often initiated by a seemingly routine task, or in many cases has no clear cause at all. As the lower 5 nerve roots exit the spinal column they join together to form the Sciatica nerve.
Sciatica refers to pain that develops as a result of compression or irritation of this nerve. As the nerve roots come together to form the Sciatic nerve – which occurs close to the spine in the upper region of the hip – the Sciatica nerve travels down the back of the leg all the way to the foot. As the nerve travels down along the back of the hip, thigh, knee, and calf it must pass between – and in some cases through – the muscles of these regions. As long as the muscles are loose and flexible, and the nerve is able to freely glide along these muscles, the nerve remains healthy. However, if the nerve becomes compressed or irritated at any point along its path from the spine to the foot, Sciatica pain can develop. It is important to realize that Sciatica refers to a group of symptoms that occur as a result of injury and irritation to the Sciatic nerve and the vertebral spinal joints the nerve exits from.
One common misconception is that Sciatica always results from a disc herniation of the lower back. Although disc herniations often result in Sciatica symptoms, they are actually one of the less common causes of Sciatica. In fact, it is much more common for Sciatica symptoms to develop as a result of vertebral joint issues, and tight muscles of the hip and leg.
Summer Activities
If you are travelling try to take your pillow with you. Also when sitting support your lower back with a small cushion or roll up a T-shirt and tuck in into the small of the back. Keep your neck straight above you shoulders by using a neck cushion while sleeping.
When gardening, try to sit on a stool, or kneel on a pillow. Use your legs to squat down; do not bend from the waist to bend down.
When painting, try to alternate the use of your arms to roll the paint. If painting the ceiling put the roller on a broom handle, this straight up but forward slightly!
Always maintain excellent body alignment with all sports! If you have questions, please ask!
