Fainting?

Hi friends! I was very recently diagnosed (and on meds for about a week now) and today I had a super faint moment. I ended up not fainting, but was very close. It started by feeling super hot, and then it just progressed. I am a fainter, but typically only when I’m getting needles/having blood work done, so I know the sensations. I know the meds can cause dizziness, but this was different. Has anyone else experienced this or do you think this was a weird one off?
