I asked this question about headaches and was pointed towards "ice pick headaches." However, I still don't feel like it exactly fits with what I feel. The headaches do last less than a minute, but rather than feel it on top of my head, I feel like this headache is coming from the inside of my brain, like a mining pick, rather than an ice one. It starts on the inside of my head and like echos, or something, outward, sometimes it reverbrates throughout my whole head, and at others I feel it only on the one side it starts on [usually on the right]. Do you have any idea what that kind of headache is called? or is this, like, a secondary symptom of something larger? I am in my twenties. It's been increasing in frequency in the past couple of days. Could this be related to stress? I've just started a new semester at University. Thanks!
