I've had headaches like never before in the past 2 months. I'm used to getting headaches when not sleeping well, stressed, or tension from sitting glaring at my screen. However, these days the pain is mainly concentrated behind my left eyeball and seems to be unresponsive to the usual painkillers.
First noticed it 2 months ago and seemed to coincide more or less with the first period I'd had in about 8 or 9 months.
I've never suffered from migraines and don't seem to have other migraine-type symptoms.
