Your spine is made up of vertebrae which have ‘discs’ in between that act as a type of shock absorber, preventing damage to your spinal tissue and bone. These discs are made of annulus fibrosus that is a tough circular fiber that surrounds a gel-like core. However, this gel-like core can be moved from the center that, when moved out of place from an injury, can cause swelling and begins to balloon out, often protruding from its place between the vertebrae.
This injury is referred to as a bulging disc and is a common spinal injury sustained to your intervertebral disc and as the condition progresses; your symptoms will become worse. Also, the annulus fibers can be torn which can often cause back or neck pain.
