treatment or no treatment?

i recently had an mri which shows a “possible 2mm microadenoma“. my prolactin levels have been elevated and i’ve had monthly blood tests to check this since August. my TSH is also slightly elevated and my oestradiol levels are low. the only reason i even found any of this out was because i got a full panel blood test because i have been suffering from unexplained vertigo/dizziness for well over a year. but i have no “normal” systems - my periods are irregular(ish) but they still come, no lactation…. the endo said i can start cabergoline “if i want” but she doesn’t recommend it because of the side effects and because everything seems to still be “ticking normally“. she doesn’t think the vertigo is caused by the microadenoma. but i’m not sure. it’s been super hard so i’m not sure what the right thing to do is.
