For five years, I have been on
synthroid and never seemed to stablize. In Jan. of this year, I had to have a bilateral dissection, (sounds like dissecting a frog!), because a needle biopsy should suspicion for papillary thyroid cancer. Well, good news is, none of the lymphnodes had cancer. Bad news is...nice scar on the neck! But since then, I have had major "anxiety". Shakiness, heart palpatations, lighthead, grumpiness etc.
