If you do have low thyroid problems then I can see why you have felt kind of OFF the last few weeks..... for the thyroid produces hormones that control a person’s metabolic rate, so in essence, the thyroid acts as the body’s gas pedal.
An over active thyroid (hyperthyroid) causes the body’s systems to run too hot and too fast, where as, an under active thyroid (hypothyroid) causes the body’s systems to run too cold and too slow.

Please by all means make the effort to go back for a follow up visit..... your doctor will be able to tell you how this can be treated - some times medicine and change in diet is all that is needed.

Good Luck....
