Headache pain is an extremely common symptom of an illness. In the majority of cases, it is caused by a viral infection, such as the common cold or flu. The patient experiences sudden or recurring episodes of a headache that can be debilitating and disruptive to day-to-day life.
The severity and location of headache pain is often a good indicator of what might be going on inside the head. There are five main types: tension, cluster, vascular, sinus and migraine. A primary care physician will typically rule out more serious causes before determining if it’s a type of headache.
These are some good signs that your headache is not due to a cold: -The pain lasts longer than three days.

A headache may last between a few hours and a few weeks. Headache pain can be mild or it can be severe. It is also possible that the headache pain goes away after some time and it never returns (known as “cluster headaches”).
Pain above the eye, pain below the eye, neck pain, scalp tenderness, nausea or vomiting, sensitivity to light – these are different signs of migraine.
Tension headaches are caused by muscle spasms in the head and neck. They are often caused by stress, anxiety, or depression.
Tension headaches can be relieved by tension-relievers like meditation, yoga, acupuncture, massage therapy, and chiropractic care.
Some tension headache episodes – κεφαλαλγίες – may be caused by dehydration or lack of sleep. Hence they can be relieved with water or drinks with caffeine in them.
