got sciatica?

Sciatica is a condition in which pain travels or radiates along the path of the sciatic nerve. This nerve is the longest and the largest in the body and it travels from the lower back down the back of the thigh to the leg and foot.

Causes

The causes of sciatica include compression of the sciatic nerve by herniated disks and bone spurs (overgrowths) from the spine. Other causes include compressing tumors and spinal stenosis which is a condition in which the nerve passages in the spine are narrowed. Infections, trauma to the nerve and conditions like diabetes which damage the nerves can also cause sciatica.

Risk factors for developing sciatica include advancing age since herniated discs and bone overgrowths are more common in the elderly. Obesity, by virtue of the fact that it increases stress on the spine, also contributes to the changes that can cause sciatica. Jobs that require the lifting of heavy objects or sitting for long durations can also predispose a person to developing sciatica.

Symptoms

Symptoms of sciatica include leg pain which can vary from a mild discomfort to an excruciating ache. This pain which usually affects just one leg, can be burning in nature or sharp like an electric shock. It can be worsened by coughing or sneezing or even sitting for long periods of time. Numbness and tingling sensations of the leg as well as muscle weakness are other symptoms of sciatica.

Diagnostic test for sciatica include x-rays of the back since these can show bone spurs. Magnetic resonance imaging (MRI) is also done to reveal the presence of herniated disks.

Treatment

Medications used to treat sciatica include non-steroidal anti-inflammatory drugs (NSAIDS) like ibuprofen and naproxen since they reduce the pain and inflammation. Narcotics like codeine are prescribed for those with more severe pain. Heat and/or ice packs are also used to relieve the pain of sciatica. These are usually applied for 20 minute durations several times during the day.
