Did you know there are over one hundred different forms of arthritis? Some forms, like osteoarthritis and rheumatoid arthritis, are common enough that most people have at least heard of them. There are other forms that are not so common. One of them is reactive arthritis. This particular form of the disease is generally the result of bacterial infection.


Diagnosing reactive arthritis is difficult. As such, patients are frequently misdiagnosed until they eventually see a rheumatologist. As a consultant rheumatologist with the NHS, reactive arthritis patients are often referred to me. I can assure you that the disease, while uncomfortable, is rarely serious.


Inflammation: The Primary Symptom


GPs may have trouble diagnosing reactive arthritis because there are no specific lab tests to confirm it. The lab tests rheumatologists rely on only rule out other conditions, thereby allowing for a reactive arthritis diagnosis. The primary symptom we look for is inflammation.


By definition, arthritis is an inflammatory disease. Reactive arthritis fits the bill. It causes inflammation in the joints, particularly the knees, ankles, feet, and wrists. Inflammation can also appear in the tendons (tendinitis), bones (enthesitis), and spine (spondylitis).


Some reactive arthritis patients complain of pain in the lower back and buttocks. Others experience heel spurs and general pain in the heels.


A Bacterial Infection


The pain is always uncomfortable, but one of the encouraging things about reactive arthritis is that it is caused by a bacterial infection. Get rid of the infection and the arthritis symptoms go away. There are only a few types of bacteria that science has thus far linked to reactive arthritis:


  • Chlamydia trachomatis
  • Salmonella
  • Shigella
  • Yersinia
  • Campylobacter


Chlamydia trachomatis is transmitted through sexual contact. It can enter the body through the vagina or urethra. The remaining four bacteria are transmitted through food. Thus, people stricken with food poisoning are at a greater risk of developing reactive arthritis.


Antibiotics and Rest


Treatment for reactive arthritis is fairly simple. If a patient still has the bacteria in their system, antibiotics will take care of it. As for the arthritis symptoms, these generally clear up over time. The best treatment for these is a combination of rest and moderate exercise.


Almost all cases of reactive arthritis resolve on their own. That being said, arthritis pain may continue for up to a year after the bacteria is eradicated. Most cases of long-term reactive arthritis pain are linked to pain in the lower back and buttocks.


Self-Care at Home


As a private rheumatologist, I may deem it appropriate to prescribe NSAIDs or corticosteroids to help manage reactive arthritis inflammation. In extreme cases, disease-modifying antirheumatic drugs may be needed to bring severe inflammation under control. But for the most part, the way to treat reactive arthritis is through self-care.


I recommend starting with a proper diet and ensuring that all food in your home is stored properly. You want to minimise the risk of reinfection through food poisoning.


Next, staying active is the best way to maintain joint flexibility until arthritis symptoms clear up. Moderate daily exercise is always appropriate. At night, making a point to get sufficient restful sleep only helps the body repair itself more fully.
