My head hurts?

Depends on details: A doctor can evaluate headaches and start treatment. Some medicines are "preventive," and others stop pain after a headache starts. Headaches are very common, and have many causes. Some are migraines and others are tension headaches. Emergencies include having a "worst headache ever," a headache that gets worse and worse as the day goes on, a headache accompanied by other major symptoms, etc...

Exercise: Agree with Dr. Kwok. It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.
