Hello! My name is***** to JustAnswer. I'm reviewing your question now, and will post back with your reply momentarily.

Your symptoms do suggest an underactive thyroid

It can be due to Carbimazole

I think you have been rightly put on a reduced dose

Hopefully these symptoms will improve in few weeks

Please do let me know if you have any other question

Can u tell what level my thyroid is now , from the T4 22.46 and TSH 0.01 is now . In nov 2019 the thyroid level was 47 !

Is the value of T4 in pmol/L?

Customer: replied 1 year ago.
I am not sure ! My hospital letter just shows the T4 22.46 and TSH 0.01 , was the result of my blood test that was done 26 05 2020 ! . Thanks for your help tonight !

Thanks for the details

Your TSH is quite suppressed and the T4 is just above normal

This can be due to the medicine and with your symptoms it seems that you may be developing hypothyroidism

So I agree with your doctor that he has reduced the dose

But I would like a repeat test in 4 weeks to see how it goes

Please do let me know if you have any other question
