Occipital Nerve Block: Preparations and FAQS

Occipital Nerve Block: Preparations and FAQS : The nerves located at the back of your head near the base of your skull are known as the occipital nerves. These nerves can result in chronic pain and headaches when they are irritated, inflamed or injured.

An occipital nerve block is used to block or numb pain resulting from occipital nerve irritation or injury. The procedure involves injecting a local anesthetic and steroids into the occipital nerve area to relieve pain.

The local anesthetic is a numbing agent that provides immediate pain relief. The steroid is an anti-inflammatory agent that helps to reduce inflammation and also provides longer-lasting pain relief.

Patients with chronic headaches and occipital neuralgia may benefit from occipital nerve block.

How occipital nerve block is done

The injection site may be numbed to reduce pain. Your doctor will insert a needle and direct it into the area between the greater and lesser occipital nerves. X-ray guidance may be used so that your doctor can see clearly the direction of the needle.

When the needle is at the right position, the medication containing local anesthetic and steroid will be delivered slowly into the area.

The procedure is short and takes only 2-3 minutes to be completed.
