I HAD MY LEFT THYROID REMOVED DUE TO A 3CM

I HAD MY LEFT THYROID REMOVED DUE TO A 3CM HURTHEL CELL NEOPLASM TUMOR WHICH WAS BEGNIN, WHEN THEY STUDIED MT WHOLE THYROID FOUND TWO MICROSCOPIC TUMORS THAT WERE CANCER. BEFORE REMOVING I WAS FEELING SEVERE FATGUIE AND WEIGHT GAIN. I AM STILL FEELING THE FATGUIE AND HAVING TROUBLE LOSING WEIGHT. I HAVE HAD MY BLOOD TESTED TWICE AND THE FIRST TIME MY TSH WAS 2.20 AND NOW ITS 3.85 BUT THE DOCTOR KEEPS TELLING MY I AM IN NORMAL RANGE THAT MY RIGHT GLAND IS PRODUCING ENOUGH HORMONE. I FEEL LIKE A ZOMBIE I CANT HANDLE FEELING EXTREMELY TIRED ALL THE TIME.
