Dizziness/Black outs

Alexa
Is anyone else extremely dizzy? If so what did your Dr. Say? I tried calling my Dr right now but they are out for about 2 hours. The last 2/3 days I have been dizzy every time I get up. I was at the store with my husband yesterday and I literally was blacking out and I couldn't hear anything like I was going deaf. Scariest moment. Any tips ?
