Number one, you should not take any pain killers if something like this happens. The most you should take is asprin which will help thin your blood in case it is a heart problem. You should call 911 or get to the ER and let them check you out especially since you have hypertension
. Also with you having pain in your jaws and sick to your stomach you should not play around with that at all.
What are you waiting for? This could save your life. If nothing else it would ease your fear if it isn't a heart problem but I wouldn't play around. Get help now!!!
