18 year old daughter has been experiencing some dizziness, lightheadedness, heart feels fluttery or like skips a beat or two. This lasts for a few seconds. This has been happening the last few days. A couple of weeks ago, same thing happened, but she saw black spots and felt faint. Again, just for a few seconds. She is away at school, so I am not sure what kind of doctor she should see. I feel like since it is happening more often now, even though not as bad as the first time, she needs to get checked out.
