I havee had constant pain in my forehead for 6 days that gradually gets worse if i cough or sneeze?

Pressure: this sounds like you may have a frontal sinus infection. You need to be examined and evaluated by your doctor.

Associated symptoms?: Headache coupled with a new cough or sneeze can sometimes be indicative of sinusitis. Do you have other symptoms such as runny nose, eye pain or fever? It is natural for a headache to get worse when we sneeze as your blood pressure and venous drainage system transiently increases. See a doctor if your headache does not abate.
