You say your doctor tested the TSH for your thyroid, well that is a pituarity blood test, and it maybe normal but you could have a thyroid problem.
You need a FreeT3, and a FreeT4, along with thyroid antibody blood tests.
This sounds like it could be Graves if it is a thyroid problem,
Make sure your doctor does the Frees in the blood test, a lot of doctors only test the TSH, for thyroid, and these doctors which just go off the TSH, just havent got a clue with thyroid disorders.
Also ask for some Thyroid Antibodies, blood tests also.
Have you also had a full blood count? if not , ask for a full blood count also at the same time.
May i ask have you lost any weight? become heat intolerant? had any palpatations?
Sorry ive asked a lot of questions , im just trying to get a better picture, so i can help you.
Hope this as helped, please keep me posted
