Spinal Cord Cells Control Pain

Chronic Pain Conditions, Chronic Pain News, Nerve Pain
Spinal cord cells are responsible for controlling pain and itch, according to research published in the journal Neuron. Researchers from the University of Zurich used genetically modified viruses to interfere with the functions of neurons in mice in order to investigate how neurons contribute to pain and itch processing. The researchers drew on prior findings from 50 years ago, which had demonstrated “Gate Control Theory” of pain – the idea that inhibitory nerve cells in the spinal cord could determine whether a pain impulse from the periphery (from the foot, for example) is relayed to the brain or suppressed. The researchers found that the spinal cord cells, located specifically in the spinal dorsal horn, use the amino acid glycine as an inhibitory messenger. By disabling the neurons, which released glycine,…

Sciatica: Hitting the right nerves 

Chronic Pain Conditions, Nerve Pain
Sciatica symptoms explain conditions around the sciatic nerve A lot of people have their lives badly affected by sciatica. Like most other conditions, you can deal with sciatica effectively with a well planned and structured exercises program. But before we go into details of specific sciatica exercises, it is first important to explain what sciatica is, as it is often misunderstood. Sciatica is a set of symptoms rather than a diagnosis in itself (meaning it does not explain the cause of the pain). Sciatica is a general term used to explain a set of symptoms around the sciatic nerve. Technically, it refers to pain caused by compression or irritation of one or more nerves exiting the lower spine that make up the sciatic nerve, and there are a number of…

Chronic Nerve Pain Linked to Anxiety & Depression

Nerve Pain
Study links brain inflammation triggered by chronic paint to anxiety and depression. Brain inflammation caused by chronic nerve pain alters activity in regions that regulate mood and motivation, suggesting for the first time that a direct biophysical link exists between long-term pain and the depression, anxiety and substance abuse seen in more than half of these patients, UC Irvine and UCLA researchers report. This breakthrough finding also points to new approaches for treating chronic pain, which is second only to bipolar disorder among illness-related causes of suicide. About a quarter of Americans suffer from chronic pain, making it the most common form of enduring illness for those under the age of 60. The Institute of Medicine estimates that this costs our society more than $635 billion per year. In work with rodents, Catherine Cahill,…

Vitamin B6 Boosts Your Mood and Your Nerves

Nerve Pain
Among vitamins, Vitamin B6 is one of the most essential vitamins for nerve health and is important for anyone suffering from painful nerve related health problems such as Neuropathy. What Are The Benefits of Vitamin B6? Vitamin B6 performs a variety of functions that are essential for your health.  According to Dee Sandquist, MS, RD, CD, a spokesperson for the American Dietetic Association, “It is important for cardiovascular, digestive, immune, muscular, and nervous system function.” Of these many benefits, the most relevant for Neuropathy patients is vitamin B6’s positive affect on nerve health.  Vitamin B6 boosts the health of nerves and is essential in maintaining a properly functioning nervous system.  A deficiency in vitamin B6 can put a strain on the nervous system and result in nerve damage. How Does It Work?…

Complex Regional Pain Syndrome (CRPS)

Chronic Pain Conditions, Nerve Pain
  Complex Regional Pain Syndrome (CRPS) is a chronic musculoskeletal pain condition affecting the arms, hands, legs, and feet, after an injury or trauma to the limb. Complex Regional Pain Syndrome (CRPS) is believed to be caused by malfunction of the peripheral and central nervous systems. Individuals have characterized CRPS as prolonged severe pain, changes to the skin, and/or swelling in the affected area. There are two common forms, CRPS-I and CRPS-II. CRPS-I patients do not have confirmed nerve injury. Patients with CRPS-II have confirmed nerve injuries. Symptoms vary in length and severity. In most cases the disease is mild and individuals recover gradually over time. The more severe cases of CRPS patients may never recover, and long-term disability can occur. CRPS is not caused by psychological factors; the constant…

Peripheral Neuropathy

Nerve Pain
What is Peripheral Neuropathy? Think of peripheral neuropathy like static on a telephone line, both interrupt the sending of information. Peripheral neuropathy is a result of nerve damage in the peripheral nervous system; causing a disruption of information from the brain and spinal cord to other parts of the body. Peripheral neuropathy can occur following traumatic injuries, infections, metabolic problems, and exposure to toxins. Diabetes is a common cause of peripheral neuropathy. Symptoms of peripheral neuropathy include muscle weakness, numbness, tingling sensations (paresthesia), loss of sensation, and pain in the feet and hands, and other parts of the body. Peripheral neuropathy can affect motor nerves (muscle control), sensory nerves (sensations), or automatic nerves (those that control heart rate, breathing, or body temperature). In chronic forms of peripheral neuropathy symptoms develop…
