Sharp Stabbing Pain In Lower Left Side Of The Back

The human back is a complex structure composed of muscles, bones, nerves, and organs, and it's not uncommon for people to experience discomfort or pain in this region from time to time. One specific type of back pain that can be particularly distressing for patients is the sharp stabbing pain in the lower left side of the back. 

If you've ever felt a sudden, intense jolt of pain in this area, you're not alone. Keep reading to explore the various causes, symptoms, diagnostic process, and treatment options for this type of pain. At Orleans Physiotherapy, Ontario, we want to provide all our patients with a greater understanding of what might be causing that painful sensation and the best ways to get better.

Understanding Back Pain

Back pain is a common problem. It can result from various factors, including muscle strains, spinal issues, or lifestyle choices. Understanding these potential causes is the first step in addressing the sharp, stabbing pain in the lower left side of the back. This is because knowing the root causes is crucial for effective management and treatment. Some of the treatment strategies often involve exercise, good posture, and, in some cases, medical intervention, but this will vary depending on the diagnosis, symptoms, and the individual patient.

Causes Of Sharp Stabbing Pain In The Lower Left Side Of The Back

Let's explore the potential culprits behind sharp/stabbing pain in the lower left side of the back. This region above the buttocks is where multiple structures converge, making it susceptible to various issues. Some of these causes include:

Muscular Causes:

  • Muscle Strains: Muscles in the lower back can be strained due to overuse, sudden movements, or poor lifting techniques. When these muscles are strained, it can cause sharp, stabbing pain for a period of time. Physical therapy is often a beneficial treatment option to resolve musculoskeletal complaints.
  • Myofascial Pain Syndrome: This condition involves the development of trigger points in the muscles and fascia, which can lead to referred pain in the lower back.

Spinal Causes:

  • Herniated Disc: A herniated or slipped disc can put pressure on the nerves in the lower back, causing sharp, shooting pain.
  • Scoliosis: Scoliosis, an abnormal curvature of the spine, can lead to imbalances in the lower back, resulting in discomfort and pain.

Organ-Related Causes:

  • Kidney Stones: Kidney stones can cause excruciating pain as they pass through the urinary tract, often radiating to the lower back. Organ-related causes of back pain like kidney stones are treated by a medical team, and in some cases specialists.
  • Diverticulitis: Inflammation of the diverticula (small pouches in the colon) can lead to pain in the lower left abdomen, which may also be felt in the back.

Nerve-Related Causes:

  • Sciatica: The sciatic nerve, which runs from the lower back down to the legs, can become irritated or compressed, causing sharp, shooting pain in the lower back and legs.
  • Pinched Nerve: A nerve in the lower back can become pinched due to conditions like spinal stenosis or herniated discs, leading to localized pain or radiating discomfort.

Lifestyle Factors:

  • Poor Posture: Slouching or maintaining poor posture for extended periods can strain the muscles and lead to discomfort in the lower back.
  • Obesity: Carrying excess weight places added stress on the lower back, increasing the risk of pain and discomfort.
  • Sedentary Lifestyle: A lack of physical activity can weaken the muscles in the lower back, making it more susceptible to pain and injury.

It's important to note that while some of these causes may resolve with time and conservative measures, others may require more intensive medical intervention. Delve deeper into the symptoms and characteristics of this type of pain, helping with differentiating between various causes of back pain.

Symptoms And Characteristics Of Back Pain 

When experiencing sharp, stabbing pain in the lower left side of your back, it's essential to pay attention to the specific symptoms and characteristics. This information can help healthcare providers like doctors and physical therapists pinpoint the cause and decide on the most suitable course of action. Some of the common signs and symptoms include:

  • Sharp vs. Dull Pain: A sharp, stabbing pain typically feels intense, sudden, and may be described as a "knife-like" sensation. Dull pain, on the other hand, tends to be more lingering and achy.
  • Location: The exact location of the pain can vary depending on the underlying cause. It may be concentrated in the lower left side of the back or radiate to the hip, buttock, or even down the leg.
  • Duration and Frequency: Take note of how long the pain lasts and how often it occurs. Pain can be brief or sporadic, and in some cases can persist for extended periods of time. 
  • Triggers and Aggravating Factors: Consider what activities or movements tend to worsen the pain. For instance, does it get worse when you bend over, stand up, or engage in physical activities? This can help the physical therapist differentiate the root causes of the pain.

Diagnosing Back Pain 

Determining the precise cause of your pain is critical for effective treatment. Healthcare providers employ various diagnostic procedures to identify the underlying issue, including:

  • Physical Examination: A thorough physical examination, including palpation of the affected area and assessment of your posture and range of motion, can offer initial insights.
  • Imaging Studies: Depending on the suspected cause, your healthcare provider may recommend one or more imaging studies such as X-rays, MRI (Magnetic Resonance Imaging), or CT (Computed Tomography) scans to visualize the spine, muscles, and surrounding structures.
  • Blood and Urine Tests: For organ-related issues like kidney stones or infections, blood and urine tests may be conducted to detect any abnormalities.
  • Electromyography (EMG) and Nerve Conduction Studies: These tests assess the electrical activity of muscles and nerves, helping identify nerve-related causes like sciatica or pinched nerves.

Treatment Options For Back Pain 

The good news is that many causes of sharp stabbing pain in the lower left side of the back can be effectively treated. The appropriate treatment plan depends on the underlying issue. Some of the common treatment options include:

Conservative Treatments:

Conservative treatments are those that don’t require surgery and can include:

  • Rest and Activity Modification: Rest and avoiding activities that exacerbate the pain can help in the healing process.
  • Physical Therapy: Physical therapy plays a pivotal role in the management and treatment of back pain. It involves a comprehensive approach to address the underlying causes and improve the patient's overall well-being. An essential aspect of physical therapy is targeted exercises and stretches.
  • Pain Medications: Over-the-counter or prescription pain relievers may be recommended by a doctor for short-term pain relief.

Invasive Procedures:

Invasive procedures are prescribed by the medical team and may include: 

  • Epidural Steroid Injections: For conditions like herniated discs or spinal stenosis, epidural injections can provide temporary pain relief.
  • Surgery: In severe cases, surgical interventions may be necessary to address issues such as herniated discs, spinal deformities, or organ-related problems. This is usually only used as a last resort for persistent and severe pain, or in the case of acute trauma (such as an accident or fall). 

Lifestyle Modifications:

Lifestyle modifications can include the following:

  • Exercise and Stretching: Regular physical activity and stretching can help prevent and alleviate pain. A physical therapist can help patients choose the best exercises for their situation.
  • Ergonomic Adjustments: Improving workplace ergonomics and lifting techniques can reduce the risk of recurrence.
  • Weight Management: Maintaining a healthy weight can alleviate stress on the lower back.

Alternative Therapies:

Some people may choose alternative therapies that include:

  • Acupuncture: Acupuncture may offer pain relief by stimulating specific points on the body.
  • Chiropractic Care: Spinal adjustments by a chiropractor can help with certain musculoskeletal issues.

Prevention Strategies For Back Pain

Prevention is always better than cure. To reduce the risk of sharp stabbing pain in the lower left side of your back, consider the following strategies:

  • Maintaining Good Posture: Be mindful of your posture, especially when sitting for long periods.
  • Staying Active and Exercising Regularly: Engage in regular physical activity to strengthen your back muscles and maintain flexibility.
  • Hydration and Diet: Drink plenty of water and maintain a balanced diet to prevent conditions like kidney stones or diverticulitis.
  • Proper Lifting Techniques: When lifting heavy objects, use proper techniques to avoid straining your back.
  • Stress Management: High stress levels can lead to muscle tension and pain. Incorporate stress-reduction techniques into your routine.
