Her TSH, T3 and T4 several months ago were all normal. For the past month she has complained almost daily of internal shakiness in her legs. It is not associated with hypoglycemia although that is one of her symptoms when her blood sugar is low. It is so bad that it will awaken her at night. The Pediatrician and her Endo have no idea what is causing it. It is making her and us crazy. She is missing school because she can't think straight when it's severe. It doesn't coincide with anything we can come up with. What do we do now?
