What Researchers Did
Researchers treated a patient with severe cluster headaches in a hyperbaric chamber on two occasions after other treatments, including conventional oxygen, had failed.
What They Found
On both occasions, the patient's pain was promptly relieved while breathing 100% oxygen at two atmospheres of pressure. This was the first reported case of a cluster headache successfully treated with hyperbaric oxygen.

Study Limitations
The primary limitation of this study is that it is a single case report, requiring further prospective studies to confirm efficacy.
