Hi, my daughter is 2, turning three in december. She has has unexplained bruises on her ears that started over the summer. One ear will have a bruise thatt is dark and covers the parts of the ear visibible on the outside and inside, not inside the ear canal as far as I can see. She has also recently decreased her eating. She sweats A LOT, very easily. soaking pillowcases even thouh no blankets are on her. Or just sweating a lot while playing with the other kids. The bruises continue coming and going and swtich ears. i KNOW for a fact the other kids are not pulling or biting her ears. and I know she hasnt hit her head on both sides of her ears back and forth for the last few months. What should I do or what could these be frtom ?
