Angie, it could just be andrenalin that caused the
shaking in your daughter, but it wouldn't hurt to have her thyroid hormones
checked. Some common symptoms of hyperthyroidism are tremors, nervousness, heat
intolerance, weight loss despite adequate appetite, excessive sweating and
palpations. My niece was only 16 when she was diagonosed with Graves disease
(hyperthyroidism). A common symptom that shows up as it progresses, is very
large looking eyes.
