I have hyperactive thyroid on and off for the last 20 years. It can go into remission for a few years and then reoccur. Everytime when the symptoms reoccur, the specialists prescribe the same drug (not the same as yours, mine is a small white pill not green and the name starts with "T" not "C" ). The doctors have warned me thyroid medication can affect the liver so that may be why your blood test shows abnormality in the liver. You should check with your doctor to find out more. BTW, please don't eat any shell fish like crab, lobster and especially oyster, they will make your hyperactive thyroid even worse! Take care.
