Tension-Type Headache, Unspecified, Intractable

Tension-type headache (TTH) refers to pain radiating from the forehead to the back of the head as a bilateral band. It often occurs without warning and spreads to the neck muscles. Patients describe it as tension, pressure, or dull pain. It is usually triggered by stress. The complexity of the processes is the biggest difficulty in diagnosing and treating TTH. Although there are genetic connections, there are no single responsible genes.
