Key Symptoms: Persistent pain and tenderness around the left elbow joint Swelling and warmth over the affected joint Stiffness, especially after periods of inactivity or in the morning Reduced range of motion in the left elbow Possible fatigue and general malaise Symptoms may fluctuate, with periods of flare-ups and remission

Diagnosis Path: Diagnosing seronegative RA involves a combination of clinical assessments and diagnostic tests, including: - Physical examination focusing on joint swelling, tenderness, and range of motion - Blood tests to rule out other conditions and check for inflammation markers, though rheumatoid factor may be absent - Imaging studies like X-rays or MRI to assess joint damage and inflammation - Applying the criteria established by rheumatology guidelines to confirm the diagnosis Diagnosis can be challenging, especially without rheumatoid factor, so a rheumatologist's expertise is often required.

Treatment Protocols: While treatment plans are personalized, common approaches include: - Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation - Disease-modifying antirheumatic drugs (DMARDs) to slow disease progression - Corticosteroids for short-term control of severe symptoms - Physical therapy to improve joint function and strength - Lifestyle modifications such as regular exercise and joint protection strategies Early and consistent management is vital to prevent joint damage and improve quality of life. Treatment decisions are made by healthcare professionals based on the severity and progression of the disease.
