You most likely have Hashimoto's Auto-Immune Thyroiditis, or Hashi, with antibodies, an
elevated TSH, nodules, swollen nodes, fatigue, cholesterol problems, fat lump, etc.... Why are you off the meds? Will they be doing surgery next month for that nodule? I know that people have to stop taking their Synthroid for surgery. I thought they could still take Cytomel, another thyroid...
