Migraine and Aura
It felt like my head was in a vice. That's how some people describe the pain of a migraine. But a migraine is much more than just a headache. It includes symptoms that happen before the pain starts and after it goes away. One of those symptoms is aura, and it can be just as debilitating as the headache itself. And auras can also slightly increase your risk of certain other conditions. More from Mayo Clinic.
