There could various reasons as to why you have chest pains and a tingling, possibly numb arm. It's not mentioned here if there are any other symptoms such as pain going up the neck and into the jaw and if they happen by day or night, or under what circumstances. As such, it would be difficult to make an accurate hypothesis as to what is actually going on. However, with symptoms like these most people would, quite naturally, fear a heart attack or similar condition amounting to heart problems, like angina for instance, and ultimately heart failure. It's worth mentioning here that heart attacks rarely actually start with chest pain, although chest pain is often regarded as symptomatic of most heart problems. Having said that, this symptom can sometimes also be caused by anxiety and stress. Another instance regarding the numbness and tingling in the arm could also be due to a variety of things, apart from the more obvious associations with heart problems, such as a trapped nerve (possibly caused by lying or sleeping awkwardly), poor circulation, a general lack of movement or even vitamin deficiency. The collective symptoms for heart problems and heart attacks and heart failure differ from person to person, a bit like fingerprints where rarely there are two sets of symptoms, although being very similar, are exactly alike. What you have described here warrants a professional examination. This is where the old adage of 'if in doubt, if worried, if symptoms persist then consult your doctor' comes in. Nothing like this should be left without being investigated further, and for peace of mind and a calmed heart, a trip down to the doctor's surgery or the A&E is what this person would prescribe.
