Possible causes of daily headaches are inflammation or other problems with the blood vessels that surround the brain, traumatic brain injuries and brain tumors. Changes in intracranial pressure and meningitis cause headaches as well. Some daily headaches are "primary" chronic headaches, which are headaches with no identifiable cause, Mayo clinic explains.
People who take pain medicine for tension or migraine headaches are at risk of developing rebound headaches, according to Mayo Clinic. These headaches occur most often when an individual takes pain medicine more than two days each week or nine days each month.
Treatment of chronic headaches due to tension or stress commonly involves over-the-counter medication such as acetaminophen, ibuprofen and aspirin, according to Mayo Clinic. Prescription medications, such as tricyclic antidepressants, are also effective in some individuals, especially when combined with alternative therapies, such as cognitive behavioral therapy, meditation, relaxation training or massage. Warm compresses, hot showers and biofeedback sometimes help as well.
Patients suffering from migraine headaches sometimes get relief by ingesting small amounts of caffeine or taking over-the-counter-medication. Resting in a dark and quiet room, or applying cold or hot compresses to the neck and head sometimes helps as well. Doctors also prescribe medicines such as sumatriptan and zolmitriptan, to treat migraine headache pain as well as preventive medicines, such as propranolol and amitriptyline, to prevent them from recurring.
