Hi,
Noted your history about left sided
chest pain in a 24 years old male, also feeling squeezing,
smoking weeds and cigarettes, burping, unhealthy diet and so on.
Since you are young the cardiac issues may not be present but yet you have to get all the cardiac check ups like EKG, X-ray chest,
Echocardiography, treadmill and soon under the guidance of a Cardiologist.
The commonest reasons can be as follows:
Costochondritis.
Muscular spasm
Stress and
anxiety related issues.
Thoracic spine related problems.
Problems related to lungs and pleura.
This can be further diagnosed by proper clinical evaluation, examination and go for a proper management.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
