I agree with the others to have a medical consult, some blood work and some diagnostic testing. Unfortunately, you really have to push and be your advocate, I cannot stress that enough. These symptoms are not normal. A friend of mine recently was having bouts of dizziness and they found a tumor the size of a lemon growing on her thyroid, thankfully it was benign. She's a thin individual so this sized mass was quite a shock to find growing in her throat area, apparently it was restricting blood flow to her brain by compressing the carotid artery, thus making her dizzy. Best of luck with it all
