Today I was getting my hair cut and started feeling really hot but figured it was just from the hairdryer. I started sweating, went pale, got dizzy, had tunnel vision, ears felt stopped up... I had to stop her three times so I could cool off but it kept happening over and over. I'm assuming my blood pressure just dropped but I didn't know if there was something I should do? Should I call my doctor? Or just tell them monday at my appointment?
