Tension Headaches. Tension-type headache is a term used to describe a headache causing mild to moderate pain that often feels like a tight band across your forehead or pressure around the head and neck. These headaches may be provoked by the stress of everyday life, eyestrain or poor posture. They are not worsened by routine activity, and therefore usually don't prevent people from going about their daily activities. Typically, the pain is not troublesome enough to cause sufferers to see a doctor.
