Hi there ~
I am sorry that you are having hypothyroidism
is usually a medication that is prescribed to help with hypothyroidism. I think that it might be the right medication for you. Please check you Thyroid function tests
regularly (TSH, T3 and T4) so as to make sure that you are getting better with you condition. You may need dose titration of the thyronorm to make you feel better.
I hope this helps. Consult an endocrinologist
Take care and have a lovely day !
