Doctors warn us that if you crack your neck a lot when trying to stretch it, you can have really serious health issues. Doctors refer to the case that recently happened to 28-year-old Josh Hader. He had a sore neck and in order to improve the situation, he started stretching his neck and tilting it from side to side. Suddenly, he heard a pop and Josh felt the left side of his body completely freeze. He also felt weak, began hiccuping non-stop, and had problems with coordination and eyesight.
