What happens internally when you move your neck a certain way, something pops then the area gets really hot for a couple minutes?
In: Biology
Your neck joint has synovial fluid in it that lubricates the joint. This fluid has gasses in it (oxygen, nitrogen etc.) When the joint is stretched (ie. your neck) the area which the fluid takes and the force on the fluid changes. This leads to the nitrogen gas bubbling out of the fluid phase, leading to the pop (ie. like bubble wrap).
