If your doctor is reluctant or dismissive of oxygen for your treatment and you have been diagnosed with cluster headaches, do not take “No” for an answer. Providing the doctor with a printout of the JAMA High-flow Oxygen Study and respectfully pressing for a rationale regarding denying the appropriate treatment will usually suffice. As in all things with a rare disease like Cluster Headaches, it’s important to build some rapport with the doctor and assume that they are working in your best interest, but may not be very familiar with this disease. If you find too much resistance, consider going to another doctor, preferably a headache specialist neurologist. If the doctor is reluctant to prescribe O2, he or she will probably be reluctant to provide you with adequate preventative medication as well. Find out more in our comprehensive oxygen guide.
