Hello doc, I had done low impact cardio exercises for 4 months for average of 4 days a week. I given 1 and half month gap which I didn't done any workout. I started again from 4 days. Yesterday night I felt heart palpitation, anxiety, left side breast bone pain while rubbing with fingers on it and felt the same today also. I went for an ecg. Please go through the report and suggest should I continue with the same ??? Anything to worry ? Is ecg enough or should I go for further investigations??? Thank you.
