Hi all, I am a 24 year old male without much history of headaches except for the occasional hangover or tension headache. Two days ago, I had a headache that was out of nowhere and moderately painful, which may or may not be related to the pains I've been having for the 2 full days since then. All of yesterday and today, I have had headaches that hit and fade over about 5-10 seconds. They come in regular intervals, about every 10 minutes. Has anyone ever heard of anything like this? They are not debilitating, but they make me stop what I'm doing for a few seconds, and are concerning because I've never experienced anything like this. Unlike my past headaches (including the one before these brief pains started) these are in the same place every time and aren't caused/worsened by standing up or an obvious cause like dehydration.
