Headaches are a common problem and are generally transient and eased by a mild analgesic such as tablets containing a combination of paracetamol or aspirin with codeine. More than 90 %of all headaches are classified as tension headaches, which occur when the muscles in the back of your neck and/or scalp tighten.  Sometimes they can be relieved by lying down at the first hint of a headache in a dark room, drinking cool water and placing a cold pack over the head and face.
