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
Hello Marie, the kind of pain you described more likely due a transient neural (nerve) compression because of the position of your arm, cardiac pain is more dull aching like heaviness in the chest, which will be persistent.  So be assured, however because a week has gone by, and you are still anxious, it would be ok if you can get a EKG done, which will give us some idea about the heart.  Regards Chat Doctor.
