My daughter tested high for TSH, she is 6 years old. My question is she complains of sore legs, mainly at bedtime, it seems to be behind her knees. She also says her hand hurts when writing, it seems to me possibly to be in the tendons. She has a list of symptoms mainly extreme tiredness, but I wondered if this could be related. We are seeing a consultant on Wednesday to go over her latest bloods and see if the raised TSH could have been due to viral infection. There is definitely something wrong with her.
