I have a pain in my neck since I was a little girl like 8 ? It is a very sharp intense pain I get it 2 or 3 times a yr this yr it was 2 this mo.it is very sharp like someone is stabing you or a really bad cramp where inches below where you feel your heart rate in my vein? I cant figure this out ? my sister suffered a stroke recently and said her veins in her neck have a quite bit of plaque she is only 25 I am 27 and I worry I could have the same and that this is genetic ?
