hello, I'm a 38-year-old man who has had chest pains for the last 2 years, but in the last year pains appeared in my left shoulder, which have subsided. Now I have chest pains and I can't breathe deeply, I don't cough, I haven't lost weight in the last year I did 6 chest x-rays, scales detected pulmonary sequelae from tuberculosis that I had 15 years ago plus spirometry that detected a mild restrictive syndrome but currently I have permanent chest pains and it's like I can't breathe deeply I also did cardiological investigations that except the heart, I don't know what else to do
