Joint pain can be categorized into two main types: inflammatory and non-inflammatory arthritis. Inflammatory arthritis, like rheumatoid arthritis, typically worsens with immobility and causes morning stiffness. Non-inflammatory arthritis, such as osteoarthritis, often gets worse with motion and is relieved by rest. The pattern of joint involvement can also differ, with inflammatory arthritis often being symmetrical and non-inflammatory arthritis usually asymmetrical.

Polyarticular pain often comes with other symptoms that can help narrow down the diagnosis. Weakness might indicate a neurological or muscle-related disorder. Fever, night sweats, and weight loss could point to a systemic illness. Some conditions, like lupus or psoriatic arthritis, may cause skin rashes or eye problems. Paying attention to these additional symptoms is like putting together pieces of a puzzle to reveal the bigger picture of what's causing your joint pain.

The duration of your symptoms can be a crucial clue. If you've been experiencing joint pain for less than six weeks, it could be due to a viral infection or the early stages of a systemic disease. Pain lasting longer than six weeks is more likely to indicate a chronic condition. Think of it like solving a mystery - the timeline of your symptoms is an important piece of evidence.

Polyarticular pain can have various causes, and a thorough evaluation is crucial for proper diagnosis and treatment.
