Certain types of inflammatory arthritis and fibromyalgia are often confused because their symptoms mimic one another in early stages.

Distinguishing between the two to yield a proper diagnosis is important to ensure proper treatment. Both are chronic disorders earmarked by long-lasting pain.

Inflammatory Arthritis

There are several types of inflammatory arthritis which include:

  • rheumatoid arthritis
  • ankylosing spondylitis
  • lupus
  • psoriatic arthritis

Inflammatory arthritis leads to inflammation of the joints and surrounding tissues. Long-standing inflammatory arthritis can result in joint deformation and disability.

Fibromyalgia

Fibromyalgia affects not only joints, but muscles, tendons, and other soft tissues in the elbows, hips, chest, knees, lower back, neck, and shoulders. Fibromyalgia can develop alone or with inflammatory arthritis.

Common Shared Symptoms

Both fibromyalgia and inflammatory arthritis sufferers have pain and stiffness in the morning. Other common symptoms shared by the two conditions include:

  • fatigue
  • sleep disturbances
  • limited range of motion
  • numbness or tingling

Diagnosing Symptoms

Tests to distinguish fibromyalgia and inflammatory arthritis include X-rays, blood tests, and ultrasound. Besides inflammatory arthritis, fibromyalgia also shares common symptoms with several other conditions.

  • chronic fatigue syndrome
  • cancer
  • depression
  • HIV infection
  • hyperthyroidism
  • irritable bowel syndrome
  • Lyme disease
