I am 51 years old woman. My weight is 60 kg. I have hypothroism and was on 50 mcg thyronorm, but due to TSH level 5.54, doctor recommended me 75 mcg for the last two months. Now a days, I  feel rapid heart beat, nausea, increased appetite (some times), chest pain, always fatigue, severe pain in legs & feet.
Hello, I think your TSH level wasn't very high, in fact it was slightly elevated, and same dose would have been fine. Current dose is high for you. You get your TSH level done and if low, it will confirm the diagnosis and after that probably we need to reduce dosage. Also get one hemoglobin level done as well. Do you also have upper abdominal pain, bloating, burping etc? If yes it suggests gastritis and acidity problem, and you will need antacid like Pantoprazole. Hope I have answered your query. Let me know if I can assist you further.
