Hello , I appear to be in good health , a little weight gain but stays pretty steady. Had a check last year all came good. Recently this Saturday as laid down to rest for the evening, I experienced a very different issue. I rested on left side with left arm folded up by my ear and under a pillow. Some time after that I gently strength our my arm and immediately experienced a very painful pain run up my left arm, then a good hit to my chest after immediately i began to sweat cold with chills and felt light headed and dizzy and a bit nauseous. Not sure were this came from, but was worried if a mild heart attack I may have experienced. Could this be possible . From that on I am still feeling a little light headed, and nauseous with my left are just week. Was this some type of a heart attack ?? Thank you Marie Nanez
