Hello and welcome to HCM
As you have mentioned that your pelvic ultrasond and pelvic MRI
suggest presence of ovarian cysts along with feeling giddy and feeling of vomiting
The ovarian cysts may be sectring certain hormone known as beta HCG
which may be responsible for feeling of vomiting and giddiness.
I suggest you to get your hormones checked- LH, FSH and beta HCG.
If the hormonal
profile is derranged then you can get the ovarian cysts removed by surgery.
However, do visit your specialist soon.
