I have an intermittent headache consisting of a dull pain occurring in a small area on the top right of my head, It is an irregular pattern and the pain lasts for a couple of seconds at a time. It goes away for a few minutes and starts again. Started yesterday, Thursday. It is a new feeling. I have been under financial stress for several months with real estate sales and volunteering in homeless issues in my community. Yesterday, a couple of 82 mg aspirin seemed to interrupt it. I take only a 5 mg Quinapril daily. I don t recall a blow to the head. Do have an irregular sleep pattern. I exercise regularly, am 5 10 , consume alcohol very infrequently, eat organic food & will turn 75 in July. The pain is 3 or 4 of 10. Thank you!
