I HAVE BEEN ON SYNTHROID FOR ALMOST 2 YEARS FOR A UNDER & OVER ACTIVE THYROID I GO FROM 125MG FOR A FEW MONTHS AND THEN 150MG FOR A FEW MONTHS I HAVE HAD A SCAN AND ULTRA SOUND OF MY THYROID AND THERE IS A VERY SMALL MODULE (THEY ARE NOT WORRIED) THIS PAST WEEK HAS BEEN REALLY BAD AND I TRIED TO ASK MY DOCTOR IF MY STRANGE SYMPTOMS ARE FROM MY THYROID AND NO ONE CAN GIVE A STRAIGHT ANSWER... MY SYMPTOMS ARE LOSS OF APPETIATE, HEADACHE, SEVERE BURNING IN THE BACK OF MY HEAD ABOUT 5 MIN AFTER I TAKE A PILL AND LASTS PRETTY MUCH ALL DAY, SHORT OF BREATH, AND OF COURSE ALL THIS CAUSES ALOT OF STRESS AND ANXIETY. I THINK I SHOULD STOP TAKING MY PILLS PLEASE HELP ME!!!!!!!!
