Hello, I am 19 years old, do not smoke, drink ocasionally, however I drink a glass of wine every 2 days. I have experiencing a fluttering feeling in the middle of my chest, only lasts like a secon or 2, however it makes me feel like I am experiencing shortness of breath, however, it only lasts like 2 seconds. After that, there is a very slight ache in the middle of my chest, but it disappears. Wanted to know, what this is, if this is normal or dangerous, and what I can do to prevent it. I am hypochondria, so even if this is little, it really scares me! Thank you for your time, have a great day.
