My chest is uncomfortable and I always feel blocked.

Disease analysis: Hello! Judging from your age and symptoms, your condition belongs to functional chest tightness (that is, chest tightness without organic lesions). It may have something to do with your mood and environment, and it will generally ease after external factors are eliminated.

Suggestion: Chest tightness like this is a functional disease caused by emotion, which does not need to be nervous or treated. After rest, open the window for ventilation or breathe fresh air outdoors, relax and adjust your mood, and you will soon return to normal. If all this is not improved, you need to go to the hospital to check your cardiopulmonary function. I hope my answer can help you!
