Thanks for writing in to Healthcare Magic!
You have complex problems and you must carry out any modification under the supervision of a qualified physician only.
Because you have high potential of developing serious complications.
you may be having respiratory symptoms due to beta blocker
and because you had a fall in BP so the medicine needs to be adjusted/stopped but it must be judged by a physician.
You should get a fresh thyroid
function test and a clinical examination to decide on the TRT.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
