My thyroid function test
Free T3 =2.86 (2.65-5.09) pg/ml
Free T4 =0.90 (0.93-1.70) ng/dl
TSH=14.64 (0.25-5.80) ulU/ml
3months ago My Tsh was 0.67 when I was taking 75 mcg thyronorm as I started feeling low heartbeat after taking medicine I started taking 50 mcg thyronorm ,so what should I do now? I am just 19 years old.
