Lower back pain. constant need to crack back, to the point where i will feel uncomfortable in my skin. i try to resist cracking but i often fail.

Facets: When people talk about " popping" their back in a similar manner as when people do it with their knuckles, this usually involves the facet joints; which are small joints that run up and down each side of the back. Similar to cracking your knuckles, the etiology is not well understood, but may be related to a build up of nitrogen in the capsule of the joint.
