for the past three weeks, i have been having "fainting spells" one of the times, i was at the doctors after recieving a shot, another time i was at the tanning salon and had to end my session early because i felt a fainting episode coming on. this week, i was in class i was dizzy, nauseaus, and started to get warm. i thought i was going to pass out while sitting down. i stood up to leave the class, but i started to lose my sight, so i sat down... not wanting to make a scene in the class. later that day i had another episode losing my sense of hearing. it has been 2 days since i have fainted. i still feel really nauseated, have a really bad headache, and feel exhausted.
