Is it normal that after doing ice i feel tingles throughout my body?

So yes, they feel like tingles, but more like electric shocks running through my body. They can occur in my brain, or arms, or legs, sometimes starting at my head and running down to my feet. At first they are more intense and recur very often with very short intervals, slowly subsiding away as the days pass. They aren't unpleasant at all, and don't hurt a bit. I've heard different stories as what this could be, but I am curious, has anyone shared the same experience, and what do you speculate it to be due to?

-No lectures please, I have reasons for everything I do, and you are just wasting your time seriously.

More info: They can last for 2 days, (or 3) and smoking ice makes them shocks more intense, whereas compared to oral ingestion-not that intense and lasting but I still get them and enjoy them the same. And this is ice, not crank or cut meth, it's the crystal.
