I have have been getting a lot of preassure in my head. During the time of the preassure I sometimes feel nauseated, get headaches, and lately chronic nosebleeds. Sometimes I feel dizzy as well. When I have all the symptoms at the same time I feel like it s hard to function and I can t think. Today not only did I have all of these symptoms but I also was talking to someone else I could hear them but it sounded like there was a wind storm so it made it hard to hear them.
