My daughter has been up and down for 3 nights, she has a low grade fever and I thought she was just trying to get her top two teeth, but after she fell asleep, I took a flashlight and opened her mouth to take a look at how close they were to coming through and there is a whitish bubble blister right under her nose, where the line between her top two teeth will be, then, on her pallate there is a white line about 1/4 inch long that looks a little blistered up too. Her fever is still coming and going. I was going to take her to the dr today but someone told me it could be like a blood blister from teething? Thanks for your time.
