Greater, and Lesser Occipital Nerve Block
- Purpose of Procedure – To reduce headache in the back of the head.
- Procedure Overview – Irritation of the nerve can lead to headache. Injection is both diagnostic and for treatment.
- Procedure Details – In the office you will lie on belly, or sit up in a chair with your forehead on the table. The area in the back of the head will be cleansed. A small needle is then used to block the nerve. An anesthetic, and a steroid are usually used. The injection usually takes less than a minute.
- Before the Procedure – The physician will examine for the area of tenderness. There is no need to hold any medications you may be taking.
- After the Procedure – The anesthetic will usually have effect for a few hours, and the steroid will have effect starting in a few days. Occasionally pain is increased for a few days before it gets better. Icing the area for 20 minutes per hour can reduce post injection tenderness.
- Procedure Risks – Potential, but unlikely risks include elevated blood sugars, rash, itching, weight gain, extra energy, soreness at the site of injection, bleeding.
