Doctor let me ask, the last few days I have pain in the middle of my chest, shortness of breath, hot face with a feeling of nervousness, fatigue is a warning sign of what disease? Thank you doctor!

I am a 20 year old female. About 1-2 months ago, I often had pain in the middle of my chest. The first time usually happens early in the morning to wake up or late at night. After receiving the covid vaccine, for about a month now, I have pain sometimes during the day.
