Arms numb and swollen tongue

while watching tv one night both of my arms went numb. and I felt like a rush of blood went straight to my head. about 30 sec later I was talking a bit funny asthough my tongue was swollen. I thought I had food allergy. I went to the doctor and he said I had to get an ekg. The ekg said it was a minor stroke. he said that my pressure read normal on one and high on the other. my grandmother died of a stroke and my father just had a stroke less than a year ago. should I worry or is this an anxiety attack? thank you
