I normally rely on it as part of my treatment for clusters, and not being able to access it during the pandemic made them so much worse. I normally go to community acupuncture, which is on a sliding scale with the goal of allowing you to go as often as EVERY DAY (which I did). note, this is also how people access acupuncture in China, so if you're going once a week in the US for a severe issue you're not getting the treatment you should be getting. Not only did acupuncture reduce frequency of headaches, but it also shortened my headache cycle and gave me a place to sleep during the day. I do not use it as acute treatment during a headache, but during cluster cycles. Acupuncture probably saved my life when I was misdiagnosed and given the wrong medication.
I'm currently living in Armenia and trying to figure out how to get acupuncture for my current headache cycle here. Give it a go. It is part of effective treatment for me, and might be for you, too.
