Tingling feeling in left arm like it is asleep, but not quite. Can feel heart beat. Tensed up feeling in left side of chest, occasional small pains mostly going from shoulder towards center of chest. In previous cases, heart beat very fast and/or hard.
Thanks for your question on Chat Doctor. I can understand your concern. Left sided chest pain, radiating pain in the left arm and fast heart beats are more suggestive of heart diseases like Coronary artery disease (CAD). So immediately consult cardiologist and get done 1. ECG 2. 2d echo 3. Stress test (trade mill test) 4. If required Coronary Angiography. If all these are normal than no need to worry about CAD or other heart diseases. Sometimes stress and anxiety can cause similar symptoms. So avoid stress and tension, be relaxed and calm. Don't worry, you will be alright, but first rule out cardiac diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
