Hi...I seem to have swollen glands high, next to my throat. Thyroid? Parathyroin? My twin sister has has Graves disease and has had her thyroid removed...My maternal grandmother also had GD. My oldest sister had two separate parathyroid surgeries several yrs. apart for growths on them. Ea. time she experienced bizzare psychotic episodes. I have been under more stress lately...more depressed...argumentative...Could there be a link/or hereditary connection?
