So my parents noticed that one side of my neck was larger than the other and I went and got tested. The doctor gave me almost a year of thyroid medicine, but I showed no symptons beside the neck. Then I went to another doctor and he said I might have the graves disease and I got blood checked and he gave me more thyroid medicine. After taking it for 2 months I went back and got checked and the blood results were good and he told me to take it for a few more months and then he said I should be fine and took me off the medication. Then a few months later I began experiencing that my mouth was dry all the time even when I am drinking water. I thought it would go away but it's been months now and my mouth is feeling quite dry. Which type of doctor should I go see to check my problem? I got bloodtested and they said it wasn't diabetes, so they don't know what it is.
