I have been prescribed Levothyroxine for hypothyroidism (mild) and have been on it for about 2 months. The first couple of weeks I felt more energetic, lost a few pounds. After two weeks, however, my symptoms have returned, tiredness, feeling cold, depressed as well as some new symptoms such as hair loss, muscle weakness, bleeding gums and weight gain. My doctor says TSH levels are good. Should I look into changing my medication or discontinuing it?
