30 year old female/
I have had constant head pressure for the past couple months. Each episode lasts 2-4 days at a time. I remember blurred vision once or twice and a dizzy spell or two. I've had an accident about 4 years ago and suffered a light concussion, but have had no problems since until now.
I am a smoker and have a "smoker's cough" and each time I cough the pressure in my head feels like it will burst.
Could this be serious, what tests should I get done to rule out any potentially dangerous causes?
