Ultrasound revealed enlarged thyroid , nodule found, get biopsy this week. Bloodwork is coming back fine even though specialist has me getting antibodies checked. Woke up this morning feeling great then while out felt very faint, got trembly, chills came on and lasted a bit. Laid down for a bit, now I m feeling slightly nauseous, slight headache, and dizzy, but not so much so. Any ideas??????
