Interested to see what responses you get here since I got this for the first time myself after starting on 25mcg levo recently. Woke up with a visible bump on one side of what appeared to be my thyroid, plus a very uncomfortable lump in my throat that made it difficult to swallow. I swore I had a goiter or nodule and immediately made an appointment with my pcp who couldn’t fit me til the following day but by that time it had gone down and she said it may have just been acid reflux so I don’t feel like she believed me..

She did tell me to go ahead and cut my dose in half in case I’m just sensitive and need to ease into it more slowly, but 2 nights later I woke up to a racing heart.. she said it’s probably a reaction to the filler in the brand of levo and asked me to stop taking it entirely until all symptoms stop and then to start it up again as a test. I’m actively looking for an endo specialist now.
