hi ive just been told my thyroid levels are low. my t4 level was 10.4 where it shud of been 12 i think the dr said my tsh level was 1. something dr said this was normal but was rising. so he put me on 25mcg of levothyroxine to take. is there anything i need to no. do i have to request something about the t3 level or do i not need to worry about it. i find it all very confusing. the only reason i had my thyroid checked was due to awful dizziness which has been constant since january feels like brain fog now but it was like everything was moving before which left me bedridden. i would really appreciate some advice. im a 24 year old female. thank you.
