Headache/Circulation
For the past year, I have occasionally experienced a short, sharp headache in my forehead that occurs when I quickly bend down (head forward), do push-ups, cough, or even on roller coasters with negative G-forces. I exercise, do not smoke, and have normal blood pressure. Initially, I thought it might be related to my sinus cavity, but the results, including the MRI, were negative. It is likely related to a brief increase in blood pressure. What could this be, and which doctor would be responsible for this?
