I was rushed to an emergency since I was experiencing chest pain on left side. ECG was normal, so was referred to general physician who gave me some antiacid and anti gas medicines for 3 days. The pain got better in 2days time. I consulted a cardiologist next day and got all heart tests done - everything was normal. He also suggested the same medicines. I still have pain and today it again shot up to the extent that I thought I should rush to emergency again. I ate something and took antiacid medicine and the pain is lesser but still there. I am really worried and in pain. Is it really gas? I don't have pain anywhere else just the left chest. Which doctor should I consult for better treatment?
