Since march i have getting a feeling of fullness and sharp pain in one specific part of my head. The area is on top of my head at the back and sort of to the left. Anyway I saw my doctor and he did a ct scan, but without contrast. I am really worried that i might have an anuerysm or something serious. The pain comes and goes and lasts about 10 min. at a time. Lately it has been getting more frequent and more intense. I am a 16 year old male. There is one more piece of information, not sure if it might have something to do with this but I had an Intercranial hemmerahge when I was a few years old.
