Understanding Back Pain, Sciatica and Lumbago

Recently, 40% of the Americans reported suffering lower back pain in the past twelve months. The causes can be many, where the importance of a good diagnosis. Below are the details of the origins of the lower part of the back pain.

The scenario is unfortunately too classic: you bend to lace up your shoes and an electric shock iterates you to the leg. Your back simply comes to remember you of the many years of neglect and reckless effort.

Backache happens when you are suffering from Lumbar Plexus Neuralgia. It is often the core of the vertebral disc - or a fragment of it - just be expelled from the fibrous ring. This action releases enzymes (including phospholipase A2) to very strong inflammatory power. The pain would be, above all, the result of inflammation of the nerve root by these enzymes.

All the irritated nerve compression maintains the phenomenon.

If the hernia is located in the posterior part of the disc, it may be in contact with the spinal nerve. It then electric shock by irritation and compression of the nerve, and the pain can spread throughout this nerve.

According to Glen Johnson of SciaticaSOS, if the vertebral floor of the nerve root is affected, it may be sciatica (sciatic nerve that innervates the posterior thigh and leg).


The history of back pain is still the same, with some variations. You drop your wallet, bends over to pick it up and rises abruptly. Here you bend forward in the impossibility to get up, grimacing in pain at the slightest movement. Has this ever happened to you?

It is simply a beginning of lumbago with the first appearance of disc deterioration. Disc deterioration occurs most of the time as you lift a heavy object. We are then folded in two, with stiff legs, buttocks in the air.

The disc nucleus is immediately compressed by several hundred pounds, and then violently pushed back during the lifting effort. It is at this moment that in moving the disc nucleus is torn along with layers of fibrous rings. Pain is then caused by irritation of the fibers of the sinu-vertebral nerve that innervates the periphery of the disc. The pain causes a defensive reaction, where the painful contraction muscles back.

Posterior articular origin lumbago

The vertebrates are articulated between them through intervertebral disk and two joints. In all movements, these joints play the role of a guide, the mechanical stresses being supported.

Low back pain is due to these posterior joints overloading or undergoing a prolonged pressure resulting from a bad position. They can occur in children and adolescents by an increase in lumbar lordosis, especially among young girls or with sports enthusiasts.

Among seniors, the absence of alternating compression and decompression of the intervertebral disc quickly alters the cartilage surface of the joint and it is the beginning of osteoarthritis.

The overload often comes from excess weight, but also a degeneration (aging of the disk). Therefore, the disk instead of playing its role, the weight of the whole body is then supported by the posterior joints. It is then that painful inflammatory reactions may result from hyperactivity imposed joint and which cause irritation, back pain and sciatica (pain in the lower back and legs).
