<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have recently within the past month started feeling what feels like a lump in my throat and its not painful but it feels like my throat is closing and is feeling like my throat may close all together. I recently quit smoking 2 months ago and am also an on again off again bulimic and i dont know if either of those would be causes of the lump in the throat but thought i would throw that out there. Also I am always extremely cold and fatigued and recently have gained about 20 pounds out of nowhere. I havent changed my diet too much but I know I started eating a little more when I quit smoking so maybe that doesnt matter but do you think I have a thyroid issue possibly?
