Polyarthritis symptoms include pain, swelling, redness, warmth, and restricted joint movement, according to Right Diagnosis. Polyarthritis symptoms are simultaneously present in five or more joints.
Unlike common arthritis, which is typically associated with joint trauma or age, polyarthritis is usually associated with an autoimmune condition, and may be experienced at any age, explains Right Diagnosis. Polyarthritis can be caused by an auto-immune disorder such as rheumatoid arthritis, amyloidosis, psoriatic arthritis or lupus erythematosus. It can also be caused by infection with an alphavirus, or by certain cancers.
The most common symptoms of polyarthritis run parallel to those of arthritis, and include pain, swelling, redness, warmth and restricted movement. Other symptoms include a feeling of bogginess in the joint and visible deformation in the joint, as well as extra articular manifestations outside of the afflicted joints, with visible symptoms in the lung, blood vessels and eyes.
Because polyarthritis simply describes arthritis that has manifested in five or more joints, the root causes and treatment of the condition remain varied and nonspecific. Physicians may recommend physiotherapy for polyarthritis stemming from joint degeneration or trauma, and push for more aggressive treatment options if the root cause of the symptoms is viral or cancerous.
