Hello to all respected doctors, i have been dealing with the problem of fatigue, irritation, high touch sensitivity, anxiety, depression and brain fog symptoms for a long time, i have asked questions about them in a previous query but i saw a doctor and he said to get myself thyroid test done my TSH id 4.80 and my free t3 and t3 t4 are at normal range but many doctors and patients says that the optimal range of the thyroid is below 2.5 or 2 and for adult like myself who is 21 year old the range may also be different, is there any chance that this level of tsh is causing me the symptoms and what should be my next step, consulting a psychiatrist or an endocrinologist. (My tsh was 5.56 in 2024).
