What can cause middle back pain on the left side? 

Left side middle back pain can be caused by many things from muscle strain to underlying medical conditions. Here’s a breakdown of the causes, symptoms, diagnosis, treatment and prevention.

Common Causes of Left-Sided Middle Back Pain

1. Muscle Strain:
   • Overuse: Repetitive movements or lifting can strain the muscles.
   • Poor Posture: Slouching or sitting can put extra pressure on the muscles and ligaments.
2. Injury:
   • Trauma: Falls, accidents or sports injuries can damage the muscles or ligaments.
   • Herniated Discs: Discs can bulge or rupture and cause pain that can radiate to the back.
3. Spinal Conditions:
   • Scoliosis: Abnormal curvature of the spine can cause uneven pressure and pain.
   • Osteoarthritis: Degeneration of the joints can cause pain and stiffness in the back.
4. Nerve Issues:
   • Pinched Nerve: Compression of nerves in the spine can cause pain that radiates to the back or limbs.
   • Sciatica: Although typically associated with lower back pain, sciatica can also be felt in the middle back.
5. Internal Organ Issues:
   • Kidney Problems: Conditions like kidney stones or infections can cause referred pain in the back.
   • Pneumonia or Pleural Effusion: Lung related conditions can cause pain that radiates to the back especially if the left lung is affected.
6. Digestive Issues:
   • Gastritis or Ulcers: Stomach related conditions can cause pain that feels like it’s coming from the back.
   • Pancreatitis: Inflammation of the pancreas can cause referred pain to the back.
7. Cardiovascular Issues:
   • Heart Conditions: Although more commonly associated with left sided chest pain, some heart conditions can cause back pain.
8. Psychological Factors:
   • Stress and Anxiety: Can cause muscle tension and back pain.
   • Depression: Chronic pain can be a symptom of depression and can affect posture and movement.

Symptoms of Left-Sided Middle Back Pain

• Localized Pain: Sharp, aching or throbbing on the left side.
• Radiating Pain: Pain that goes to the shoulder, arm or abdomen.
• Muscle Tightness: Stiffness or tension in the muscles around the spine.
• Numbness or Tingling: If nerves are affected.
• Difficulty Breathing: If it’s a lung related condition.
• Fever or Chills: If it’s an infection or other systemic issue.

Diagnosis

Diagnosing left side middle back pain typically involves:

1. Medical History: The doc will go over your medical history and symptoms.
2. Physical Exam: Physical exam will include posture, range of motion and tender areas.
3. Imaging Tests:
   • X-rays: Will show fractures or degenerative changes.
   • MRI or CT Scans: Will show soft tissues, discs and nerves.
4. Blood Tests: May be ordered to rule out infections, inflammation or other underlying conditions.

Treatment Options

Treatment for left side middle back pain depends on the underlying cause:

1. Conservative Treatments:
   • Rest: Avoid activities that make the pain worse.
   • Physical Therapy: Strengthening and stretching exercises.
   • Heat/Ice Therapy: Heat can relax muscles, ice can reduce inflammation.
2. Medications:
   • Pain Relievers: Over the counter meds like ibuprofen or acetaminophen.
   • Muscle Relaxants: To relieve muscle spasms.
   • Prescription Medications: In some cases stronger meds or corticosteroids.
3. Interventional Procedures:
   • Epidural Steroid Injections: To reduce inflammation around the nerves.
   • Nerve Blocks: For specific pain relief.
4. Surgery:
   • Considered when conservative treatments fail, especially for structural issues like herniated discs.
5. Alternative Therapies:
   • Chiropractic Care: To realign the spine.
   • Acupuncture: To relieve pain through pressure points.

Prevention Strategies

1. Good Posture: Proper alignment while sitting, standing and lifting can reduce back strain.
2. Stay Active: Regular exercise strengthens back and core muscles.
3. Ergonomics: Use supportive furniture and arrange workspaces to reduce strain.
4. Stay Hydrated: Hydration is key to spinal health.
5. Manage Stress: Yoga and mindfulness can reduce muscle tension.

When to See a Doc

You should see a healthcare provider if:

• The pain lasts for more than a few weeks.
• There are signs of serious conditions (fever, unexplained weight loss).
• You have numbness or tingling in your limbs.
• You have difficulty with bowel or bladder control.
