Hi, my bloodwork just came back 'normal' but I have a large (visible) nodule on neck, severe sweating, 40 lb weight loss in 8 months, and no period for 8 months. I'm 38. My doc wants me to see endocrinologist asap, but can't get in for a month! Having difficulty swallowing, feels like food is getting stuck in throat...help! I'm nervous it could be thyroid cancer and want to get it biopsied soon, any suggestions?
