Excruciating headache... causes?
for the past 3 months, i have been getting headaches everyday.. some days they are just vague and a dull pain, other days, they are excruciating to the point where i have to take pain killers and just pass out so that i don't throw up just from being in so much pain. also, when i get the excrutiating ones, my right eye twitches, and i sometimes get blurred vision dizziness. i also get this pulsating feeling and sound in my ears, and you can feel it on the side of my head. I'm going to see a doctor about it... i just would like to know if there is anything i should bring up what should i expect.
