Patients who have frequent episodes of pain in the upper right side of the head are considered to have a predominantly functional nature, such as headaches due to migraine or neurasthenia, which can also manifest as pain in the upper right side of the head when they are under high mental tension and high stress for a long period of time and do not receive adequate rest. However, these headaches often have obvious triggers, the relevant causative factors can be clearly identified, and they can be easily corrected and improved. However, if the pain in the upper right side of the head persists and progressively worsens, it cannot be ruled out that it is caused by brain tumors, brain occupations, and other factors. Therefore, if this condition is not relieved continuously, patients should consult a hospital to improve head CT or head MRI to rule out headaches caused by these serious problems.
