Hyperthyroid

Gu

My mom has Graves' disease and I was having symptoms of it so I decided to go to the health fair and get my tsh checked it came back 0.00 with anything under 0.30 being low. Yesterday at my sons appointment i asked my doctor and he said it was a good call on my part for thinking to test it he felt my thyroid said it's definitely enlarged and he wants to have me repeat my TSH and do T3 and a T4 in a month. Anyone else having thyroid issues?
