Hi there
I don't really know where to put this question, but I am starting to think my health anxiety is creeping up on me again.
I am having weird headaches for the last week - every time I cough I get a sharp pain over the left half of my head all the way to the front - immediately with the cough. Very painful at the exact moment I cough then dulling down afterwards. I can trigger the cough at will, but this is starting to frighten me. And I am getting worried to clear my throat!

I have made the fatal error of googling, but can anyone tell me the most likely cause??
