Hi, my mum had her thyroid removed 2 years ago. She had a large goiter and many small nodules surrounding her thyroid. She is on medication however, we have noticed within the last 6 months her being overly hyperactive in her emotions and actions eg repeating what she has to do all day, talking non stop, getting worked up when not coping with achieving her goals. She tries to do everything all at once like she is on fast forward. Can this be a side effect of her medication?
