I m peril-menopausal, have a couple of fibroids found recently after 2 episodes of unexplained constant heavy bleeding. After 7 days of the first episode, I started to feel dizziness/vertigo. This hasn t stopped. Its not severe, but daily I feel weird vertigo flashes. I am 50..soon to be 51. I take Sertraline for anxiety disorder. Have done so for couple of years now. What s the likely cause of dizzy feelings? My youngest sister has MS, which my Uncle, Mums brother succumbed to years ago. I doubt if its related to my problem though. Possibly, I have low B12, or low blood pressure?
