Nerve blocks are pain relievers that are injected into a part of the body to block the passage of impulses along a nerve. These are administered in case the pain is intense and unbearable. The following article provides information on nerve blocks that are used for alleviating neck pain.

The term 'nerve block' refers to nerve-numbing medication (anesthetic or anti-inflammatory injection), that helps in providing pain relief in the targeted region. These substances work by blocking the nerve pathways, that relay pain messages from the affected area to the brain. A group of nerves called plexus are responsible for causing pain in a particular region of the body. These medicines block these nerves, thereby reducing the pain. If the patient wishes to numb his pain, then the doctor can administer a single shot of injection containing the medication. However, if he/she wishes for pain relief longer than that, then, a medical device called catheter is placed in the affected region. With the help of this device, the patient gets a continuous supply of the pain-relieving medication.

Cervical Epidural

Cervical epidural is the type of nerve block, that is administered for relieving pain in the neck region. The spine and nerve roots in the neck have a membrane like covering, known as the dura mater, which is the outermost and toughest of the three membranes (meninges). This membrane is surrounded by epidural space, which is a space that lies in the path of the nerves that travel to the neck, shoulder, and arms. So, any kind of nerve damage in the neck, due to injury or some medical condition, causes pain in this space. When the drug is injected into the epidural space, it interferes with the pain messages that are communicated to the brain, thereby reducing the pain.

Benefits and Side Effects

The benefits of this drug include:

• Temporary reduction in the pain, that helps one to perform routine activities, which would be difficult otherwise.
• Reduction in inflammation of the damaged nerves.
• Helping in determining the 'epicenter' of the pain.
• It also helps the doctor to draw a conclusion, as to how would a long-term treatment plan work for the patient.
• Helps in providing short-term pain relief post surgery.
• May help to determine a specific cause of the pain.

The possible risks involved with its use include:

• The site of administration of the drug may become sore or infected.
• Some people may suffer from elevated blood sugar level, which can be a major concern for diabetic patients.
• Bleeding may occur in some cases.
• The medication may get accidentally delivered to the nerves, which are not meant to be treated.
• Weight gain may occur in some patients.

The drugs have different actions in different patients depending on the ailment. In some people, the effect of the medication is short-lived, while in some cases patient might not experience any relief from pain. Also, depending upon the results, the use can be discontinued after consulting the doctor. In some cases, where this approach does not work, the doctor may recommend an alternative.
