Thanks for your question on Health Care Magic. I can understand your situation and problem. Left sided chest pain should be first investigated for heart diseases. So better to get done blood pressure monitoring, ecg and 2d echo. If all are normal than no need to worry for cardiac diseases. Sometimes gastritis caduceus similar kind of itching and left sided chest pain. So avoid stress and tension. Avoid hot and spicy food. Avoid large meals, instead take frequent small meals. Avoid junk food. Start proton pump inhibitors. Quit smoking and alcohol if you have these habits. Don t worry, you will be alright, but first rule out heart diseases. Hope I have solved your query. Wish you good health. Thanks.
