Shortness of breath and worsening symptoms since reducing T3

[Guest guest]

My thyroid was tested prior to an unrelated op and I have been told the results

show suppressed TSH, high and out of range FT3 and FT4 and antibodies also

present. As a result my op has been postponed and my liothyronine reduced by

10mcg to 30mcg but my levothyroxine is staying at 150mcg until FT3 is brought

under control.

I started suffering from shortness of breath within a few hours of decreasing my

liothyronine and in the 8 days since taking the lower dose this symptom seems to

be worsening. This symptom is present all the time, even when sitting down or

inactive; I feel like I can't open my lungs all the way. I'm also more tired

and fall asleep earlier in the evenings, I have an increased aching in my legs

when walking up the stairs in our house.

I definitely feel worse now I'm on the lower dose and with a further proposed

reduction in a week I'm getting worried. I only suffered shortness of breath on

my previous levels if I did exercise.

I told the doctor about my shortness of breath and she told me it was

psychosomatic.

I also take sertraline; I don't know I this has an affect on my thyroid.

Can anyone advise on how to manage the breathlessness and if it is a known side

affect when reducing the liothyronine? If I know these symptoms are normal

'withdrawal' side affects and wont last will make this easier to bear. Any

opinions on why I felt ok when clinically hyper but I felt no obvious symptoms

to indicate hyperthyroid?

Thank you.
