When the soft, gel-like center of your vertebral disc starts to push outward against the disc’s harder outer layer, this can result in a bulging disc.
Such a condition can cause significant pain, and if some of the disc’s fluid leaks out, your symptoms can become more intense and cause numbness or sharp pain in the extremities.
Bulging discs are caused by a number of different factors, including injury or trauma. When we experience a fall or trauma, this can impact the spine and cause vertebral compression, which can apply pressure to your spinal discs and form a herniated, or bulging, disc.
In many cases, the natural effects of aging can cause herniated discs. When we get older, we lose some of the fluid in the spinal discs — this gives the discs less “bounce,” and leads to weakening of the discs.
Any condition which adds pressure to the spine can cause a herniated disc to form, including obesity, a sedentary lifestyle, and repetitive motion.
