Hi thanks for contacting health care magic.... If excess stress situation or lack of sleep is there headache can occur.... Ear problem can lead reffered headache.... As you are having periodic headache and right sided that is on one side , it could be from migraine..... Sometime in migraine aura can be present that is feeling abnormal sensation or smell or tingling before attack.... It is usually precipitate by light and loud noise. Get your blood pressure also checked.... While having headache naproxen or brufen can given..... Avoid precipitating factors like ...... -stress -bright light and loud noise -inadequate sleep -skipped meal -smoking etc. Topical application or inhalation of peppermint oil useful... Yoga , massage good one.... If still headache worsening consult psychiatrist or physician for detail examination... Take care.
