underactive thyroid
"Since being diagnosed with "Hypothyroidism"(1999). 1st was given antidepressents for being tired and gaining weight (eyeroll). Have been on 88mcg's of *Synthroid-daily.My blood work has always come back with my TSH at the HIGH-end of normal.  Former Dr retired years ago so no continuum of care (walk in clinic). Recently new   Dr suggested we adjust meds to bring down the TSH level. Started with 100mcg *Levothyroxine 5 days & Synthroid 88-2 days a week.In a few months time I suffered some pretty severe side effects-EXTREME dizziness/weakness,lack of energy,mood extremes,weight is either climbing or stagnant,racing pulse/heartrate.We checked levels & now TSH reads at the extreme low end of normal.I'm scared please help."
