NICE has said gammaCore can be used in the NHS for cluster headache.
Evidence shows people who use it had fewer, less intense headaches. It could also mean needing less medication.
gammaCore is a portable device. You apply a conductive gel to your neck. Then you hold it against your neck over the vagus nerve. It produces a small electric current, which stimulates the vagus nerve and may relieve pain.
