I AM HAVING PAINS IN THE MIDDLE OF MY CHEST.

I AM HAVING PAINS IN THE MIDDLE OF MY CHEST. I HAVE GERD. BUT THESE PAINS ARE NOT A BURN AS MUCH AS A SPASM FEEL. TODAY I CAME HOME TO WORK IN MY OFFICE AND I HAD TO GET UP AND WALK AROUND. I ALSO WAS SWEATY.

LAST NIGHT I WOKE UP WITH THESE PAINS AS WELL. THEY LAST 15 TO 30 MINUTES. IS THIS THE START OF A HEART ATTACK?
