The actual pain of a headache may result from contraction of muscles in the scalp, face or neck, blood vessel dilation in the head, or brain swelling that stretches the brain’s coverings. Another source of headache pain is that the nerves in the face or head are irritated.
If you want to find out the cause, start keeping a diary to see what triggers your headaches.
