Hernia is a disease related to displacement of intervertebral dises. Our spine is made up of 24 vertebrae, including 7 cervical, 12 thoracic and 5 lumbar. Between each of them: an intervertebral disc, a sort of cushioned. This disc is composed of two elements: a central core (nucleus) surrounded by a fibrous ring (annulus) that connects the two vertebrae to each other.

If the ring cracks, the core material protrudes outside the spine. This is called a herniated disc. This overflow of the intervertebral disc can then cause compression of a nerve root or spinal cord.
The most common herniated disc for men than women. It usually occurs between 35 and 55 years due to overwork, to lift a heavy load or after a twist of the trunk. Pregnancy and obesity are also risk factors. Genetic predisposition are often the cause of early cases, from the age of 20 years.
I have been dealing with lower back pain for a few years now. I have had epidural shots and been treated with pain medication. My herniated disks are in the l4 l5 of the spine. Those shots didn’t last very long unfortunately…only like a week or so.
