Arthritis is a general term for inflammatory joint disease, which can manifest through several common symptoms regardless of the underlying cause. These include:

  • Pain and Stiffness: Joint pain is a primary indicator, often accompanied by stiffness, which is frequently most pronounced when the affected person wakes up.123
  • Swelling and Heat: Inflammation often leads to visible swelling and increased warmth in the affected area.13
  • Redness: Some redness of the skin surrounding the joint may occur.1
  • Effusion: The accumulation of fluid within the joint cavity is a common clinical finding.1

As the inflammation progresses, it can cause severe damage to joint cartilage and underlying bone. This destruction may lead to the formation of adhesions and, eventually, ankylosisβ€”a condition where the joint becomes fused and loses its mobility. In some cases, the weakening of supporting structures like ligaments and tendons can result in joint instability or partial dislocation. Because these symptoms can lead to permanent disability and deformity, early diagnosis and appropriate management are essential for preserving joint function.123
