Hello Thanks for writing to us with your health concern. If you have normal laboratory tests for thyroid, then why do you need to take medications ? The common symptoms could be due to another unrelated illness. IT could be flu, viral illness, generalized malaise due to fever, anemia , vitamin deficiency etc. Get yourself tested for the same. You can take general multivitamin preparations ( for example A to Z capsules daily ) for general well being. Also consume lots of fresh green leafy vegetables, fresh fruits, milk, dairy products, sprouts, nuts , tomatoes, oranges, kiwi , berries etc. Exercise regularly. Indulge in de stressing regimens such as yoga or meditation. Just because you have a family history of thyroid disease, that does not mean that you need to have it. IF the tests are normal, then just do not worry. All the best. Take care.
