hi debbieliv, lilyann here, i was originally told that my cough was due to thyroid issues, back in 2020, long story short. 2023, two operations for thyroid cancer, coughing on the operating table for heavens sake and guess what..........2024......still coughing. so i do hope yours is only from a cold. wishing the best for you. i do have to say though.........levothyroxine........is from my reading...only for the thyroid hormones you need because of removal of the thyroid. i did try to not have the 2nd operation, but the surgeon wouldn't hear of it. i did have the cancer on the left side, it was radical surgery on the right side with the big nodule that had grown from 2020. take care and thanks for the "like". wishing you the best.
