I am experiencing discomfort in my throat and upper right side of my chest. I have felt a lumpin my throat for approx a year. I assumed it was because of my thyroid goiter. Byopsy has came back begign. But, my discomfort is increasing. For the past month and a half, Ive had Chronic scratchy throat, deeper voice change. When I breath in, I feel like I'm breathing in cold air. I have been feeling bad, headache, cold sweats. Slight nausea, dizziness. I went to my primary whith my concerns and he sent me to the emergency room. I recieved,MRI,X-ray and EKG. All came back ok. I am still feeling bad. Can you give me some advice on what I should do next
