Suggest Treatment For Thyroid Problems And Lump In Throat

Hello Im 45 yrs old and have been having problems with my thyroid. Weight loss, diffilculting swallowing as there is a lump in my throat which causes me to choke when eating. Thyroid levels show somewhat normal and doctor didnt put me any meds. told me to go see a specialists as he didnt know my problem. Its very scary as I have all the symptoms for hyperactive thyroid. Someone told me to gargle salt water. That sounds crazy. What do you think? Please tell me what to do. I done lost 12 pounds and Im a petite woman anyway. I weigh now at 103pounds. Im very scared. My throat usually swells in the evening and you can see it bulging out. Please tell me what i need to do. Thanks a bunch.
