Mostly on the left side. They start around my eye socket and create a ton of pressure, and then radiate on just the left side of my head. Usually lasts for a few hours. I then get a little break, but usually a tension headache pops up. Then it starts over again in a few hours.

Thats the vast majority. The ones that wake me up at night are in the back of my head. At the very crown of my head, just a pulsating headache like im being held upside down and the blood rushes to my head kind of throb. Usually followed by a left side migraine.

I occasionally get a temple to temple headache, which I assume is a tension headache.
