What is the cause of chest pain?

Question
Hello doctor,
The story is that in the past, I had heavy labor for a period of time, I had a sharp pain in my left chest, the first two days I felt only a little pain, until the 4th day, I stopped working and also I don't feel better, then it hurts more when I take a deep breath and press on my chest, and I can't walk normally.
I went to the district hospital for an echocardiogram and an X-ray, the doctor diagnosed that I had myocardial ischemia, the doctor gave me a course of medication, and I felt a little better and gradually it has been 10 months now but From time to time, I still feel a sharp pain in the left chest, sometimes the pain can last up to a few days, but it's only a little bit painful, I even feel numbness in my left arm, but it's not too heavy, so I don't mind going to work normally until now. It's been a while so I'm worried. I've been monitoring myself for so long, but it's not completely gone.
So the doctor asked me what is the cause of angina? I don't know if my disease is due to myocardial ischemia? Please advise, thank you.
