I get these headaches that come on suddenly and feels like the veins on front top of my head are being painfully pulled up - with painful pressure on my head, like my head is in a vise. It's a sharp pain that lasts for a few seconds, but it makes me dizzy. The bridge of my nose seems swollen. I have gotten this 3 times within the last month or so.
I'm not sure if it's a sinus headache, a tension headache or something more severe.
