Talk to Endocrinologist on Thyroid Disorder

Greetings. I had been diagnosed with hypothyroidism last year 2017. I started with levothyroxine soda 50microgram which was increased to 100microgram three months later. I felt better, but since many months i am feeling that my condition is not improving. I have a doubt whether the right dose is selected or not, and if thyroid is actually the problem. Want to consult with an expert.
