I get a wierd popping along one side of my head, should I be concerned?

More specifically, it is either the right or the left back of my head, and it feels really hot when it happens. This time, when it happened, instead of the after sensation gradually fading off, it held intensely for a few minutes, then vision went a little blurry for a little bit, and the right side of my face was slightly numb/tingly if that makes sense. Also, this time the back right under part of my head was numb/tingly too. This has happened on and off since I was 10, although the frequency has gotten alot worse in the last few years. It switches sides of my head too. I dont have alot of money and i dont want to find out this is nothing. Any ideas?
