Although headaches and migraines can be excruciating, emotionally-draining, and sometimes downright scary, most headaches (ex: tension, migraine, cluster, and sinus) are benign or harmless. Most forms of headaches can be treated with medications or other therapies, and no permanent damage results. When someone experiences a headache, it is usually not the result of a brain tumor, stroke, or ruptured aneurysm. Well, well---tell that to the pain inside your head!
