If anyone is reading this please help. I have a horrbile metallic taste in my mouth all the time. I have had constant dizziness for a two days and my neck hurts. Im so scared its a tumor. Ive been to the on call doctor today who only checked my chest and ears. My eye test and blood test came back fine and so did my urine test but this thought just wont go away. I really need help and some reassurance because i am freaking out!
