Sciatica is a type of pain that radiates within the path of the sciatic nerve, which is the largest nerve that spreads from the lower back to your hips and down to the back of both left and right legs. Many people confuse sciatica with general back pain, but it is important to know that sciatica is not limited to the back because it affects the widest and longest nerve of our body, meaning sciatica can occur in your back, hips, buttock, and legs.
The most common cause of sciatica is a compressed nerve in the lower spine, usually when a herniated disk compresses part of the nerve. When that happens, the affected leg will experience pain, inflammation, and numbness. Irritation of the roots of the lower lumbar and lumbosacral spine can also cause sciatica. The following are some other conditions that can cause sciatica:
In normal condition, the body cells grow, divide and form a new cell. As the body grows, there will be an increased rate of cell growth and division, depending upon the need. With time the cells become older; they eventually die and are replaced by the new cell formation.
When cancer occurs, the entire cell formation cycle gets collapsed. This results in abnormal cell growth, failure of older cell replacement, and continuous new cell formation. Actually, the older cell should die after maturing, replacing the new cells. In cancer, the older cells persist, and new cells are formed endlessly even though it is not necessary. These additional cells get accumulated and form a tumor.
Different types of Cancer
- Based on the specific type of cells, it is classified as follows;
- Carcinoma: When different epithelial cells form tumors, it is referred to as carcinoma in general. Based on the
Our spine is made up of a complex arrangement of ligaments, muscles, bones, and tendons, interconnected with nerves. This interconnected system makes us function properly and enables the mobility of an individual. When there is a problem within these areas, it may lead to mild, or sharp or even chronic back pain.
Who are at high risk?
- Age of the individual
- An inactive lifestyle and Lack of exercise
- A smoker
- A pregnant woman
- Bad posture
- Physical Job with a lot of heavy lifting that would put a strain on the back
- Sitting or standing for long periods of time
- Heredity factors
- Any form of accidental damages to the spinal nerves
Some symptoms to be aware of:
- Experiencing constant pain or stiffness in your spine
- Sharp local ache either in the upper back or lower back, usually occurs after finishing a heavy and tough lifting task
- Constant ache in the middle
For a start it is worth remembering a little bit of anatomy. The spinal column consists of relatively small individual bones – vertebrae located one above the other. Between the bodies of the vertebrae are the disks, due to which the axial load is softened. Paired processes form joints with the following vertebrae. Also attached to the processes are muscles and ligaments that strengthen the spine and ensure its movement.
Located one above the other holes in the vertebrae form the vertebral canal – a container for the spinal cord
The spinal cord is a continuation of the brain and consists of nerve fibers, through which commands from the brain go to our organs and muscles, and information from sensitive receptors, on the contrary, goes from the periphery to the central nervous system for processing. Despite its protective role and the strength of nature, the spine (and with it the
The human body is a complex system that comprises of several organ systems which work together in synchronization for the sustenance of life. The central nervous System (CNS) is one such crucial system made up of the brain and the spinal cord. The spinal cord is a thin, fragile, tube-like structure made of a bunch of nerves and other tissues that start from the medulla oblongata of the brain and continues down to the lumbar region of the vertebral column, close to the buttocks. The nerves function as transmission lines that carry messages from the brain to the rest of the body and vice versa. This is why we are able to move, feel pressure, control vital functions like breathing, bladder, and bowel and perceive pain.
What is Spinal Cord Injury (SCI)
Any potential damage done to the spinal cord could disrupt the required communication between the brain and
