What is an Occipital Nerve Block?
Occipital nerves are located at the base of the skull in the midline and just behind the ears. They provide sensation to the scalp. Inflammation and irritation of these nerves can cause headaches that start at the base of the skull and travel to the top of the head or to the sides along the temples. Blocking these nerves can decrease the severity and frequency of headaches that are caused by these nerves. If the blocks are successful, radiofrequency ablation or cryoablation can provide long-term relief.
