QUIZ: Could I Have Spondyloarthritis?

Updated on March 31, 2021
Article written by
Amy Isler, RN

Spondyloarthritis (SpA) is an umbrella term for several types of inflammatory arthritis that can cause chronic back pain and stiffness.1 Although SpA and fibromyalgia have different causes and treatments, they share many common features, including chronic pain, fatigue, sleep problems, decreased quality of life, anxiety, and depression. Because of these commonalities, the two conditions can often overlap and cause misdiagnosis, which leads to a delay in proper treatment and relief from symptoms.2

In a 2020 survey of 301 people with fibromyalgia, 44 also had a diagnosis of axial spondyloarthritis, a type of SpA. Of those 44 individuals, about half believed they should have received an earlier diagnosis. Thirty-nine percent reported their diagnosis was delayed because doctors believed their symptoms were caused only by fibromyalgia.3

Take the quiz to see if your symptoms could be caused by spondyloarthritis.

Symptoms

Spondyloarthritis mostly affects the spine and sacroiliac joints (joints that connect to the pelvic bone), but can also develop in other joints, tendons, and ligaments. SpA is characterized by inflammation at the site where a tendon or ligament attaches to a bone (also called an enthesis). Over time, inflammation can cause chronic back pain and stiffness.1

Typical symptoms of spondyloarthritis include:4

  • Lower back pain or buttock pain
  • Pain that is worse after rest, but improves after exercise and activity
  • Pain that causes sleep disturbances
  • Morning stiffness
  • Fatigue
  • Reduced mobility

Typical symptoms of fibromyalgia include:5

  • Stiffness, soreness, and debilitating pain throughout the body
  • Pain in the muscles and soft tissues
  • Sensitivity to touch and temperature
  • Sleep issues
  • Daytime fatigue
  • Cognitive difficulties
  • Depression and anxiety

Similarities Between Spondyloarthritis and Fibromyalgia

Both spondyloarthritis and fibromyalgia are considered rheumatic disorders associated with chronic pain, fatigue, and weakness. It has been reported that as many as 21 percent of women later diagnosed with SpA were first told they had fibromyalgia. Ongoing pain, sleep disturbances, and fatigue are common symptoms of SpA and fibromyalgia.2

Differences Between Spondyloarthritis and Fibromyalgia

While spondyloarthritis is considered a type of arthritis, fibromyalgia is classified as a nervous system disorder and affects the way pain is decoded by the central nervous system.2

Typically, people with SpA experience pain in the lower back and buttocks, while people with fibromyalgia typically experience widespread pain affecting the soft tissue and muscles.2,6 As is common with inflammatory pain, pain from SpA is often worse after periods of inactivity, such as after sleep, but improves after activity.4 Fibromyalgia pain is not associated with inflammation, and sometimes gets worse with activity.6

The differences between the two conditions may be less obvious in women — women with SpA are more likely to have widespread pain rather than pain specifically in the lower back.7 SpA is also more prevalent in men, while fibromyalgia is more prevalent in women.7,8 The different SpA symptoms in men and women, the overlap between SpA and fibromyalgia symptoms, and the lopsided gender prevalence can lead to delayed diagnosis or misdiagnosis in women with SpA.7

Both spondyloarthritis and fibromyalgia may be treated with nonsteroidal anti-inflammatory drugs (NSAIDs) and physical therapy, but from there treatment approaches diverge.9-11 Fibromyalgia is often treated with antidepressants and antiseizure drugs.9 SpA can be treated with corticosteroids, methotrexate, and biologic therapies.10

Can You Have Spondyloarthritis and Fibromyalgia?

A British study of approximately 1,500 people with axial spondyloarthritis found that 20 percent of participants also met the criteria for fibromyalgia.12 Having SpA or other types of arthritis can increase your chances of developing fibromyalgia later.2

Having both SpA and fibromyalgia together can increase the severity of symptoms and diminish quality of life. Therefore, it is suggested that people who are experiencing symptoms of fibromyalgia or SpA should be screened for both so action can be taken to treat all symptoms at the same time.12

The medicine is called Neurontin or the generic is Gabapentin. I take it as well and it helps a great deal. Taking it regularly helps a great deal and I much prefer taking it to my oxycodone.
