Anxiety is a type of stress that can cause or trigger an headache and in worst case scenario is a migraine. A migraine is a type of headache that can sometimes contain extreme pain and throbbing at one or both sides of the head. It can last for days and often works together with nausea and other worst symptoms. Scientists have proved that anxiety or emotional stress can trigger migraine directly because your hormones are not working normally. It can be acquired if you are taking driving lessons, or driving at the road and you are seeing a bright light or having a lot of tension.
