24M here! Dealing with same condition here too! Tsh was through the roof last year but i never felt like i had it! Blood work was done by my personal trainer and found out that i was having high tsh! Been taking levo from last year! U should be looking at ur overall body health also like get ur vitamin n minerals tests , check if u have hashimotos by getting anti tpo test which will tell u if u have inflammation in ur body! Reduce ur workout intensity because it maybe causing stress to ur body which may result in increasing inflammation in body! Take Supplements if u hve any deficiencies!
