A dull, achy pains felt in the area of forehead or at the sides and back of the head, could be a tension type of headache.
It can start as a first thing in the morning or late in the day after the daily stress has ceased.
Very often, the underlying cause for tension headache is depression and anxiety.
Insomnia that usually results from these conditions, adds to the frequency and intensity of headaches.
