On the right side top of my head, should I take aspirin, when I cough, or bend over I felt the pain a little but anoid?

Head pain. A severe pain in the head with coughing or bending could have a simple source, such as sinus infection or pressure, or something serious like an aneurysm, a blood vessel that could burst and cause serious damage. Please check with your physician immediately, or if the pain becomes severe, go to the emergency room.
