My daughter has had problems with her thyroid for a least 10 years,the problems was she was a teen ager and didn't take her meds when she was suppose to,now she is 27 years old ,she had cycests on her thyroid when she was 16.hasn't had them checked in years.Her neck looks swollen ,some days more than others ,was told she had hashimoto's ,but doctor never ran any tests. Just had her tsh done they ran a T3 and T4 ,said her tests were normal,but she has alot of systoms ,either her thyroid is off or its a combinations of 2 conditions. Just because your test are normal doesn't mean its normal.
