Hello I'm a 21 year old male, I was wondering what could be wrong with me. I'm really afraid that I have a brain anneurysm or a brain tumor. I have headaches, pain behind the eyes, weakness in the legs occasionally, and always seem tired I was wondering what this could be, sometimes If get a rush that goes to the head i'll start to freak out and shake. I don't smoke or do drugs. NO family history of anneursyms. Please help!
