occipital nerve block
When the occipital nerve is irritated, the pain of this irritation is felt near the eye of the same side of the head. This is known as referred pain. These nerves may also contribute to headaches. Sometimes blocking (numbing) the occipital nerve will reduce the headache in the front of the head.
The occipital nerve is located at the base of the skull and extends up the back of the head. Patients experiencing occipital neuralgia headaches, cervical arthritis or myofascial pain in the neck area may experience pain relief after an occipital nerve block.
The best responses to an occipital nerve block usually come from patients whose pain is relatively recent rather than long-standing.
If the first occipital nerve block doesn't relieve your symptoms in a week or two, it may be necessary to have a second injection. Additional nerve blocks may be done to keep the symptoms under control.
