Although headache is often identified symptoms of the flu but migraine isn’t. A viral infection , such as that of the flu may create or increase the severity of a headache or migraine disorder.

The increase of the cytokines

Cytokines are a group of molecules that are released by our immune system to assist to treat infections and injuries. Cytokines trigger your body’s inflammatory response which tells it to fight the flu or fix the muscle tear.

The release by the body from too many cytokines can be often referred to as a cytokine flood or may indicate cytokine released syndrome (CRS). A high concentration of cytokines within your body can result in excessive inflammation and pain.

The research into the relationship between cytokines and migraine continues. However, experts believe that a majority of migraines result from an abnormal inflammation response that is triggered by the immune system of your body. They are “mediators for the inflammation pathway” the cytokines are likely to are involved in migraine-related episodes.
