Question about ct findings and their longevity
Short and sweet; back in July I had a Ct done of my head due to headaches and blurry vision after being concussed in football. Now 5 months later I have had a steady headache for up to a week, very mild except for when it positions itself behind my left eye wherein it becomes moderate and no other symptoms. My doctor did not see any red flag symptoms accompanying the headache and said its probably tension and anxiety based and the only reason it has lasted this long is because I have been tense and anxious about it - catch 22 haha. Anyway I'm inclined to agree because I know that when I am distracted I don;'t feel the headache, and when I remember I had the headache it funnily enough comes back, but I would still like to know if a CT done with no abnormal findings back then would still be valid now? I couldn't really find anything about it online.
Thanks for your time
