I'm not the expert on this, and hopefully you will hear from some of them on this forum soon, but from what I've read nodules and thyroid levels have little, if anything, to do with each other. Now having a thyroid disease
like Hashi's or Graves
may lead to some tissue changes and
, as many know, you can have BOTH thyroid nodules and a thyroid disease at the same time.
Nodules are usually only found on a scan/x-ray or, if large enough, can be seen/felt on an exam.
