A restricted ability to fully bend, straighten, or rotate a joint could mean:
- Joint inflammation
- Stiffness from cartilage damage
- Muscle tightness or structural changes
When to act: Noticeable limitations in how far a joint moves—or pain when trying—should be professionally assessed.
6. Referred (Deferred) Pain
Pain from arthritis may not always occur at the site of the affected joint. For example:
- Hip arthritis may cause groin, thigh, or knee pain
- Foot arthritis may cause back or hip discomfort
- Lower back arthritis can radiate pain to the legs or knees
Why it matters: Misdiagnosed referred pain may delay arthritis treatment. Talk to your doctor about pain that feels “off” or migrates.
7. Fatigue
Feeling constantly tired—even with adequate rest—could be due to:
- Chronic inflammation taxing your immune system
- Pain interfering with sleep quality
- Reduced activity or mental strain
Fatigue is especially common in autoimmune forms of arthritis like RA or lupus.
What to monitor: If you’re exhausted despite resting well, and it’s affecting your focus or daily tasks, it’s time to investigate.
