When coughing why does your brain hurt?

Pressure: You increase pressure transiently when you cough as the veins returning blood very briefly are compressed. Frequent severe coughing can cause headache but if you experience ha with just minor coughing you could have something more serious going on.

Valsalva maneuver: The above term expresses increased pressure within chest cavity that transiently impedes venous outflow causing a temporary increase in pressure within brain and even spinal cord. Folks with migraine experience can especially note a transient discomfort.
