My new doctor suspected that my chronic migraines were triggered by sleep apnea. I was sent to the sleep clinic and found to have sleep apnea and prescribed a CPAP machine. Weirdly (or maybe not?) the machine itself seems to be triggering migraines. At first it was the mask, which tightly wrapped around the top of my head. I have now switched masks, but it seems to be the forced air through my sinuses that is triggering the migraines. Has anyone else experienced this?
