Need To Learn Causes of Back Pain? Read Here.
A very common musculoskeletal disorder is back pain. Causes of back pain can be varied, it can be something as simple as wrong posture to as traumatic as an accident. Statistically speaking, 90% of all adults will experience back pain at some point in their life. Back pain is common in the elderly but should be of concern in the young.
The most common cause of back pain is muscle strain, improper stretching, lifting heavy weights, stress, wrong posture etc. can result in muscle strain or muscle spasm. The strained muscle evokes the sensation of pain.
Another cause of pain are intervertebral disks. Intervertebral disks are fluid filled cartilaginous disks that cushion and lubricate the vertebrae. The vertebrae grind against one another resulting in pain as the disks shrink in size when people age.
Sometimes surgery is required to correct the ruptured or herniated disks that are responsible for back pain. Responsible for ruptured disks is generally trauma or excessive force.
The other causes of back pain include infection of the bone or soft tissue, sciatica, spinal stenosis, osteoarthritis etc.
Infection of the bone or cartilaginous tissue causes the tissue to swell, the swollen tissue exerts force against the spinal cord and this results in back pain.
Irritation or compression of any of the five spinal nerve roots that form the sciatic nerve is the symptom of sciatica. The pain is felt in the lower back and pelvic region. Depending on the amount of pressure applied on the nerves the intensity of pain can be measured.
Spinal stenosis is the condition in which the spinal cavity narrows and compresses the spinal cord. Mostly, it happens as a consequence of spinal degeneration that occurs with ageing. Osteoporosis, tumor or intervertebral disk herniation can sometimes cause spinal stenosis. The narrowing of the spinal cavity due to compression of the spinal cord causes pain.
The degeneration of the mechanical component of skeletal joints, namely the articular cartilage and bone is caused by osteoarthritis which is a degenerative joint disorder. Osteoarthritis generally sets in with old age but it can also be congenital or hereditary. The degradation of the joint causes swelling and chronic pain.
This sums up the basic causes of back pain.
