I'm Jessica! I'm a college student. I'm having these episodes. I've had seven like this in the past year. I have chest pains, heavy-chested feeling, neck pain, extreme migraines, double vision at times, and dizziness. I had a similar experince 3 years ago. It was a blackout, no hearing, bad heache, and heavy chest feeling but it passed in about 15 minutes. These current episodes can last up to a day now. I'm really worried it's nurological.
