Sometimes you can feel it building. Other times, it appears without warning. But not all headaches are created equal.

“There are different types of headaches. Three of the main ones are the cluster headaches, the tension type headaches and migraine headaches,” explains Dr. Aldith Lewis, a member of the Lee Physician Group.

She says cluster headaches are abrupt. “Cluster headaches are very rare. They are usually seen in men, they start at a quick onset and become very explosive or severe and usually go away in about three hours.”

The second type can be felt around the entire head. “Tension headaches tend to be pressure, they feel a tightness, they usually are on both sides, they are usually able to continue their regular activities, usually not very disabling, moderate, not severe,” adds Dr. Lewis.

The third type, migraine headaches are more centralized and can impact other regions of the body. “Usually unilateral on one side, they are usually throbbing, accompanied by nausea, vomiting, sensitivity to light or sounds, is usually disabling, they last from 4 to 72 hours,” warns Dr. Lewis.

While most headaches can be treated with over the counter medication, more intense ones like migraines may require prescription medication. Dr. Lewis says you should seek medical attention if your headaches increase or keep you from enjoying everyday activities.
