At her age you should call the surgeon and let them know what's going on.
I had a total thyroidectomy on Feb 19. I had severe nausea and headache after my surgery but it got better after 5 days. I was told by the surgeon to watch for tingling in my lips and legs due to the law calcium after the surgery. Low calcium levels happen a lot after TT but not always. Hope your grandma feels better.
