Reactive Arthritis

Reactive arthritis is a term you might come across when researching joint pain or related symptoms. But what exactly does it mean? In this article, we’ll break down the concept of reactive arthritis in plain English, ensuring you understand it completely. Reactive arthritis is a type of arthritis that occurs as a reaction to an infection somewhere else in the body. Think of it as the body’s misguided attempt to defend itself: it tries to fight off an infection but ends up attacking its own joints.

Reactive arthritis, also known as Reiter’s syndrome, is a type of inflammatory arthritis that primarily affects the joints, eyes, and urinary tract. It typically develops in response to an infection in another part of the body, most commonly the gastrointestinal or genitourinary tract. This condition can lead to pain, stiffness, and inflammation in the joints, making it important to recognize its symptoms, understand its causes, and explore available treatment options.

Types of Reactive Arthritis

Reactive arthritis isn’t a one-size-fits-all condition. Different infections lead to different types:

1. After Intestinal Infections:
   • Common Culprits: Food poisoning or infections from bacteria like Salmonella, Shigella, Yersinia, or Campylobacter.
   • Symptoms: Diarrhea followed by joint pain.
2. After Genital Infections:
   • Common Culprits: Usually due to a bacteria called Chlamydia trachomatis.
   • Symptoms: Burning sensation when urinating, followed by joint pain.
3. After Respiratory Infections:
   • Common Culprits: Usually caused by Chlamydia pneumonia, a bacteria often linked with pneumonia.
   • Symptoms: Cough, shortness of breath, and then, you guessed it, joint pain.
4. Following a Genital or Urinary Infection: Common Culprits: Chlamydia is a frequent offender here. What Happens: A few days or weeks after this infection, the knees, ankles, or feet might get swollen and painful.
5. After a Gut Infection: Common Culprits: Eating contaminated food can introduce harmful bacteria like Salmonella, Shigella, Campylobacter, or Yersinia. What Happens: If these bacteria upset your stomach and cause issues like diarrhea, don’t be surprised if your joints react later.

4. Tenderness: Your joints might feel sore when you press on them.

5. Uneven Distribution: One knee might be worse than the other. It’s like the arthritis picks favorites.

6. Heel Pain: Imagine feeling like you stepped on a lego every time you put your heel down. That’s how it can feel.

7. Back Pain: It’s not just the legs. The lower back can hurt too, especially in the morning.

8. Fatigue: It’s like you’ve run a marathon without even leaving your couch. You’re always tired.

9. Conjunctivitis (“Pink Eye”): This means red, watery eyes. It isn’t from an eye infection but from the arthritis.

10. Skin Rashes: Sometimes, your skin decides to join the party. You might notice spots or patches that are red and flaky, especially on the hands or feet.

11. Mouth Ulcers: Tiny, painful sores inside your mouth that aren’t caused by hot pizza.
