Your lower back may be so painful as a result of injury, poor posture, muscle strain, lifting things wrong.
Most low back pain is the result of an injury, such as muscle sprains or strains due to sudden movements or poor body mechanics while lifting heavy objects.
Low back pain can also be the result of certain diseases, such as: cancer of the spinal cord. a ruptured or herniated disc.
Dull back pain is back pain that is dull and aching rather than burning, stinging, or sharp.
This kind of pain can be accompanied by mild or severe muscle spasms, limited mobility, and aches in the hips and pelvis.
Common causes of dull pain in the lower back include trauma from an injury, muscle strains, or poor posture.
A herniated disk, or arthritis in the lower back can also cause aching pains. Read below for more information on causes and relief options.
Spine pain can be caused by injury to the spine, overuse of the spine misuse of the spine, too much pressure on the spine or even bad posture.
Upper and middle back pain may be caused by: Overuse, muscle strain, or injury to the muscles, ligaments, and discs that support your spine.
Poor posture. Pressure on the spinal nerves from certain problems, such as a herniated disc.
Some ways to help relieve spine pain are.
Keep Moving. You might not feel like it when you're in pain.
Stretch and Strengthen. Strong muscles, especially in your abdominal core, help support your back.
Keep Good Posture.
Maintain a Healthy Weight.
Quit Smoking.
Try Ice and Heat.
Know Your OTC Medications.
Rub on Medicated Creams.
The upper back is also called the thoracic spine.
Your thoracic spine—the upper back or mid-back region—is the most stable part of your spine.
It is very stiff, and the thoracic spine has a limited range of motion.
The S1 in your back lies between the L5 vertebra and the first bony segment at the top of the sacrum, which is sacral segment 1 (or S1).
The L5-S1 disc at the bottom of the spine lies between the L5 vertebra and the first bony segment at the top of the sacrum, which is sacral segment 1 (or S1).
S1, also called the sacral base, is the upper and wider end of the triangular-shaped sacrum. S1 consists of a body on the top with wing-shaped bones on either side, called the alae.
At the back, the S1 vertebra contains a long bony prominence called the median ridge.
Your lower back contains 5 bones.
Your lower back contains 5 vertebral bones stacked above each other with intervertebral discs in between.
These bones are connected at the back with specialized joints.
The lumbar spine connects to the thoracic spine above and the hips below.
Individual anatomical structures include2:
Vertebrae.
Your lumbar vertebrae are labeled L1 to L5, which progressively increase in size, allowing them to bear the body’s weight more effectively.
Your vertebrae protect important nervous tissues, such as your spinal cord and the cauda equina.
Discs.
A total of 5 intervertebral discs are situated between your vertebral bodies. The discs typically provide cushioning and shock-absorbing functions to protect your vertebrae during spinal movements.
Facet joints. Your vertebrae are connected in the back of the spine with paired facet joints.
These joints provide stability and allow your spine to move in different directions.
The joint surfaces are lined by cartilage for smooth movements.
The facets of the upper lumbar vertebrae are similar to the thoracic facet joints and allow more back and forth spinal movements.
The facets of the lower lumbar spine are more flexible and facilitate side-to-side movements.
The muscles in the small of your back are called the spinalis muscles which are closest to your spine.
They're the smallest of the paraspinal muscles, and they help you bend backward and side to side.
They also allow you to rotate at the waist.
Other muscles in your back include.
Latissimus dorsi (lats), which helps you extend and rotate your shoulder and arm.
Levator scapulae, which raises your scapula (shoulder blade).
Rhomboids, two muscles (the rhomboid major and minor) that work together to pull the scapula inward toward the spine.
The small of the back is called the small of the back because it's smaller and narrower than the rest of it.
The small of the back is the lower part of the back that is smaller and narrower than the rest.
The small of the back is also the lumbar region of the back.
The human back, also called the dorsum, is the large posterior area of the human body, rising from the top of the buttocks to the back of the neck.
It is the surface of the body opposite from the chest and the abdomen.
The vertebral column runs the length of the back and creates a central area of recession.
The breadth of the back is created by the shoulders at the top and the pelvis at the bottom.
The central feature of the human back is the vertebral column, specifically the length from the top of the thoracic vertebrae to the bottom of the lumbar vertebrae, which houses the spinal cord in its spinal canal, and which generally has some curvature that gives shape to the back.
The ribcage extends from the spine at the top of the back (with the top of the ribcage corresponding to the T1 vertebra), more than halfway down the length of the back, leaving an area with less protection between the bottom of the ribcage and the hips.
The width of the back at the top is defined by the scapula, the broad, flat bones of the shoulders.
The fifth lumbar spine vertebrae (L5) is part of the greater lumbar region.
To the human eye, this is the curve just above the buttocks, which is also commonly referred to as the small of the back.
