Lower Back Pain – Symptoms, Causes & Risk Factors

The Lumbar Spine

Lower back or the lumbar spine is an exceptionally well-designed structure with the interconnection of bones, joints, nerves, ligaments, and all muscles. They work together to provide support, strength, and flexibility. Even though it is a complex and rigid structure it leaves the lower back sensitive to injury and pain.

The lower back(lumbar spine)  bears the weight of the upper body and provides flexibility for everyday motions like bending and twisting. The muscles located in the lower back are responsible for the flexibleness and rotation of the hip while walking and also supports the spinal column. Nerves in the lower back help in sensation and also provide power to the muscles in the pelvis, legs, and feet.

About 80% of adults are experiencing lower back pain at a certain point of time in their life. It is one of the most common causes in people doing a job and it is a leading contributor in missing work days. Both men and women are affected by this lower back pain. It can range from a dull, constant ache to a sudden, sharp and severe pain that can leave a person disabled.

  • When your job involved in lifting, pulling things which can twist the spine or sitting for a long period of time may contribute to back pain.

  • Poor posture while using a computer
  • Choosing a very hunched or bowed sitting position when using computers can result in increased back and shoulder problems over time.
  • Muscle tension & Muscle spasm
  • Injuries, fractures, or falls
  • Strained muscles or ligaments and damaged disks
  • Over-stretching of your back
  • Bending awkwardly or bending for a long period of time
  • Straining your neck forward when driving or using a computer without any break

Structural Problems

Herniated Disc or Slipped Disc: The spine’s vertebrae is covered by gel-like substances that are likely to wear and tear due to ageing or injuries. A vulnerable disc may be compressed or bulge (herniation), due to pressure which causes low back pain.

Sciatica:  Compression of the sciatic nerve( the large nerve that travels through the buttocks to back of the leg causes shock-like or burning lower back pain associated with pain from the buttocks to down the leg and often reaches the foot. 

Spinal stenosis: It is a condition of narrowing the spinal column which exerts extra pressure on the spinal cord and nerves. This can cause pain or numbness in the lower back while walking and over time weakness your legs, sensory loss.

Arthritis: Arthritis including Osteoarthritis and rheumatoid arthritis causes joint problems in the hip, lower back, and some other places which leads to low back pain.

Osteoporosis: It is a metabolic bone disease that progressively decreases the bone density & strength and becomes brittle and porous which can lead to severe fractures of the vertebrae.

Some other structural problems like Spondylitis, Kyphosis etc. also the reasons for lower back pain.

Back Pain Due To Medical Conditions

Some medical conditions can lead to back pain.

Cauda equina syndrome: Cauda equina syndrome is a serious and also rare condition of a ruptured disc. It occurs when the disc is forcibly pushed into the spinal canal and the bundle of lumbar and sacral nerve roots are compressed, which can cause loss of control over bladder and bowel movements. If this condition is left untreated, it may result In permanent neurological damage.

Tumours:  Tumors cause back pain rarely. Hardly, tumours may begin in the back, but more often they are the result of cancer which has spread from other parts of the body.

Infection To Spine: Infections rarely cause back pain. However, some infections can cause low back pain when the vertebrae are involved and the condition is called as osteomyelitis, discitis when the intervertebral discs infected and sacroiliitis where the sacroiliac joints joining the lower spine to the pelvis.

Other infections: Some other infections like Pelvic inflammatory disease(PID), shingles, bladder infections can also lead to back pain.

Sleep disorders: People with sleeping disorders are more prone to encounter back pain problems compared to other people.

Endometriosis, Fibromyalgia, PMS problems, Prostatitis, abortions, uterine prolapse, obesity, ectopic pregnancy and many more underlying causes can lead to lower back pain.

Risk Factors Involved In Back Pain

Age: As people grow older they lose bone density, which can lead to fractures, and muscle elasticity is also lost. Typically low back pain occurs between the age of 30 and 50. Back pain becomes very common with increasing age.

Fitness level: Back pain most commonly occurs among the people who are physically not fit. The weak back might not support the spine properly.

Pregnancy: Pregnancy can also cause low back pain as a result of pelvic changes and changes in weight.
