Key Symptoms: Swelling and tenderness in the left wrist Pain or discomfort during movement or at rest Stiffness, especially in the morning or after periods of inactivity Limited range of motion in the affected joint Possible redness or warmth around the joint Occasional low-grade fever or fatigue in some cases Asymmetrical involvement, primarily affecting the left wrist in this context
Diagnostic & Treatment
Diagnosis Path: Medical history review focusing on symptom duration and joint involvement Physical examination to assess joint swelling, tenderness, and range of motion Blood tests such as inflammatory markers (ESR, CRP) to detect inflammation Rheumatoid factor (RF) and antinuclear antibody (ANA) testing to differentiate from other forms of arthritis Imaging studies like X-rays or MRI of the wrist to evaluate joint damage or inflammation Excluding other causes of joint swelling, such as infections or trauma
Treatment Protocols: Nonsteroidal anti-inflammatory drugs (NSAIDs) to decrease pain and inflammation Disease-modifying antirheumatic drugs (DMARDs), such as methotrexate, in more persistent cases Corticosteroids, administered locally or systemically, to control severe inflammation Physical therapy to maintain joint mobility and strength Occupational therapy to assist with daily activities and adapt to functional limitations Regular monitoring and follow-up with healthcare providers to adjust treatment plans
