Back Pain, also known as Backache, is the pain that is felt anywhere in the region extending between the top of the buttocks and the back of the neck and shoulders. It is a condition that affects most people at some point in their lives and is a common cause of disability and reduced quality of life.

Is Back Pain a Medical emergency?

Back Pain is not a medical emergency.

Types

It may be classified depending on the section of the back that is affected as follows:

  • Neck or cervical pain
  • Mid  or thoracic pain
  • Lower or lumbar pain - This is the most commonly seen Back Pain.
  • Coccydynia or tail bone or sacral pain

Based on the duration of the pain, backache may be:

  • Acute - Lasts less than 6 weeks
  • Sub-acute - Lasts between 6 weeks to 12 weeks
  • Chronic - Lasts for more than 12 weeks

Causes

The majority of the complaints of backache are due to non-specific causes while in a few cases the pain might be due to an internal cause and due to the involvement of nerves, bones, and/or soft tissues.

Some of the causes include:

  • Non-specific causes - In over 90% of the cases
  • Vertebral Compression fractures - 4% of the cases
  • Ruptured or bulging discs
  • Metastatic cancer - <1%
  • Infections of the spine - Such as spinal osteomyelitis, or abscess
  • Muscle or ligament strain
  • Arthritis
  • Osteoporosis
  • Skeletal Irregularities or deformities
  • Cauda equina
  • Referred pain from internal organs such as kidney, urinary bladder, pancreas
  • Low backache of pregnancy

Risk factors

Some of the risk factors for developing include:

  • Age - The risk of developing backache increases with increasing age.
  • Smoking
  • Lack of exercise and sedentary lifestyle
  • Obesity
  • Poor posture
  • Improper lifting of weights
  • Illness or medical conditions such as arthritis, cancer, etc.

Triggering factors

Trauma, weather changes, or sudden jerky movements can sometimes trigger backache.

Signs & symptoms

Symptoms and signs may include one or a combination of the following:

  • Muscle pain and soreness.
  • Intense shooting or stabbing pain or dull pain.
  • Pain that travels to either the buttocks and the legs, or to the neck and the shoulders.
  • Pain that worsens when bending, moving, or lifting weights.
  • Pain that lessens with rest.

Investigations

Some of the investigations that may be done include:

  • Laboratory tests including blood test: To evaluate the presence of infections or other conditions that could be causing the pain.
  • Imaging tests:
    • X-rays
    • CT scan
    • MRI
    • Bone scans - to evaluate the presence of bone tumors or compression fractures.
    • Nerve conduction tests/electromyography (EMG) to evaluate the presence of any nerve compression.

Diagnosis

The diagnosis of backache and the evaluation of its cause are done with the help of medical history, clinical evaluation, and results of the investigations done.

Treatment options

The management of backache is aimed at treating the underlying cause, providing relief from the symptoms, and restoring activity. It may involve self-care, physical therapy, medication, and surgical intervention is required.

Medical management

The medical management of back may include the following:

  • Over the counter analgesics - To provide relief from backache.
  • Muscle relaxants - For moderate to severe backache
  • Topical pain relievers
  • Opioid analgesics - For severe pain that is acute backache or sub-acute backache
  • Tricyclic antidepressants - For chronic backache
  • Spinal (Epidural) injections - For that has not responded to other medication

Interventional including surgery and indications for surgery

Surgical intervention may be required for certain conditions that affect the spine such as spinal trauma, disc compression, etc.

Surgical procedures may include:

  • Discectomies
  • Disc replacement surgeries
  • Spinal fusion surgeries

Role of diet/ Exercise/ Lifestyle changes/ Preventive measures

Physical therapy can play an important role in the management of backache and may include:

  • Heat therapy - Useful in back spasms
  • Ultrasound stimulation of muscles
  • Electrical stimulation of muscles
  • Muscle strengthening and stretching
  • Regular physical exercise

Other lifestyle changes that can help to prevent backache are:

  • Cessation of smoking
  • Maintaining an ideal body weight
  • Regular exercise that helps to build muscle strength and flexibility

Complications

Impaired quality of life and impaired mobility are the most major complications.

Prognosis

The prognosis for backache is generally good, and in cases where the underlying cause is cancer or a metastatic tumor, the prognosis is usually poor.

When to contact the doctor or hospital? / How to identify the emergency or complications?

It is advisable to seek medical attention, if the symptoms are present or if the pain is continuing to worsen in spite of therapy.

Indications for hospitalization if required

Hospitalization is usually not required. But maybe needed if surgical intervention is required.

Suggested clinical specialist/ Departments to consult for this condition

Backache may be attended to initially by a family physician, and subsequently by a neurologist, orthopedist, physical therapist, and a spine surgeon.
