It's hard to explain to anyone who's never had a migraine just what a migraine is and how severe the pain can be. But a migraine is much more than just a bad headache. This in turn activates the pain receptors in your brain. The cause of this process is unknown, but doctors do know that several changes may happen in your body before a migraine strikes.
Some people experience what is known as an aura or prodrome shortly before the pain starts.
During this time, symptoms seemingly unrelated to a headache may occur. These symptoms include changes in mood, feeling nauseous, seeing shimmering or flashing lights, and even having blind spots. According to leading migraine experts, treating your migraine before symptoms become severe may help to reduce the severity of the migraine and is a highly recommended approach. It can be difficult but if you check below, you'll be able to use this chart to see which headache seems the most like yours.
