When I was at my friends last night I all of a sudden felt abit dizzy like I might faint. I came home and still felt like this even abit sick. Today my head feels abit fuzzy and my ears feel blocked like when you've been on an airplane or something? What do you think it is? Iv been doing a lot of walking outside lately do you think it could be a head cold that hasn't come through yet or because I was tired? I don't think my anxiety about it is helping.
