Brain Hemorrhage:

Internal bleeding in the brain leads to decreased oxygen supply to the brain cells. The constant bleeding creates pressure in the brain and causes ischemic necrosis which results in Post-Traumatic Headache.

Certain chemicals in the brain known as neurotransmitters are responsible for mood elevation. Due to a traumatic Injury the imbalance between these chemicals particularly substance P and Serotonin results in the development of a Headache.
