Hello, There are some factors causing headache: - bad teeth: get them checked by a dentist - bad positioning : try to correct posture especially when using tv or computers; - lack of physical activity: should go out and take short walks breathing fresh air - stress: try to cope with stress - bad eating habits: do not skip meals, try to eat healthy - too much caffeine: coffee might be good in waking you up but sometimes causing irritations ending to headaches - anemia: get a complete blood count to rule that out - ear problems: get them checked by ENT specialist - dehydration: check blood electrolytes and replace them adequately as per test results. To me, should check your teeth first. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Albana Sejdini, General & Family Physician
