What Causes Cyst On Thyroid Along With Nodules On Eyelids?

I already know that I have an 8mm cyst on my Thyroid. It has shown on MRI s for years. The MRI were for unrelated issue-Disc problems. I haven t gone to my Primary, yet. I believe the cyst has activated (for lack of a term). I have nodles, both eye lids, both collar bones and niay inside elbow. I can eat anything and not gain weight, I eat all the time, but I m not really hungry. I just do it. I m 5 6 , 135 lbs, I DID lose 25 lbs 3 years ago, in like 2 months. I had everything checked, pelvic C.A.T scan. I was fine. I believe the tes(Endocrinologist, primary , MRI s and blood work will be diagnosed as hyPERthroidism. I also don t settle down easily...always getting up, speeding around. I don t mind. I am quite content being so productive but drives husband crazy. What do think? Hyperthyroidism? Eye nodules came first, 3 months ago
