Sounds like you’re in a little bit of a messy medical situation. It sounds like you may have a Thyroid condition as swelling is not normal. You may have nodules on your thyroid or it could just be that you have Hashimoto’s with Hypothyroidism and need hormone medication like Synthroid or Levothyroxine to control the Hypothyroidism. If you have nodules on your Thyroid, you may need surgery to remove them, but they will most likely be watched initially after being diagnosed. They could also be malignant and need to come out. My daughter had a 6 1/2 hour surgery to remove her thyroid and several nodules due to thyroid cancer. Non-smoker as well and she is doing well 3 years post surgery. Don’t play around with your health here, it could be dangerous. I would also find a new Endocrinologist that specializes in Thyroid conditions. Yours is not helping you at all!
