I have been having ear fullness along with dizziness and fuzzy feelings in my head my eyes seems as though they are always adjusting. I can t workout too long because I began to feel lightheaded for an example when you stand up too fast and everything is black for 3 seconds or so. I don t know what is wrong. It started in 2012 and since then I have went to ENT eye doctor and got blood tests and everything seems to be fine? I also have jaw discomfort a lot and it seems as though when I eat my jaws get tired and they throb for at least an hour after. Ive always had headaches since I was 6 years old but most of my headaches are in the back of my head close by my ears. I feel very down often I can t concentrate and I get frustrated quickly and I m always having anxiety attacks now. I m a 23 year old female and need answers.
