Hi, i have been dizzy for the past 5 months now, first one day i had vertigo dizziness, and from that moment i feel a bit dizzy every single day. i am scared to go anywhere because i am off balance most of the time. i especially feel dizzy when i get my period, i have to stay in the bed for 2 days.
