Hello doctor, I am 37 years old this year, pain in my left chest, occurs 2 years ago, sometimes but not often. Since the first symptom appeared 5 times now, I can't breathe. I want to ask the doctor what is this disease and is it dangerous?

I have pain in my left chest and fatigue in my left shoulder blade. So the doctor asked me if the left chest pain and left shoulder fatigue are okay? I just had chest pain on the left side on the morning of February 28, 2021, I didn't have it before. I hope you can answer, thank you doctor.

I have signs of tightness and sharp pain in my left chest, my heart rate suddenly beats fast even though I am not worried or nervous. So the doctor let me ask women pain, left chest tightness, fast heart rate, what are the signs of disease? Thank you doctor.

I am 36 years old this year. Recently, I feel something tight in my left chest (feeling like something is pressing on my chest, uncomfortable), causing anxiety and insomnia. There are times of anxiety, rapid heartbeat, cold in the body and tremors in the limbs.
