[|AI|]  Thanks for your question on Chat Doctor. In my opinion it is muscular pain mostly due to exercise.  But since it is left sided chest discomfort, we need to rule out cardiac cause first. So get done ECG. It will come normal mostly as you are too young for cardiac disease.  But better to rule out this by ECG. Try to follow these steps for better symptomatic relief. 1. Avoid heavy weight lifting and strenuous exercise. 2. Avoid bad postures in sleep. 3. Take good painkiller and muscle relaxant. 4. Apply warm water pad on affected site.
