What is rheumatoid arthritis? These symptoms tell you

I believe many people often hear middle-aged and elderly people around them complain about joint pain. In fact, most joint pain is caused by rheumatoid arthritis, especially when the weather is bad, the symptoms of this pain are particularly obvious. So, clinically, what is rheumatoid arthritis and what are its specific manifestations?

Rheumatoid arthritis

Rheumatic arthritis is a common acute or chronic connective tissue inflammation. Rheumatic arthritis should broadly include rheumatoid arthritis. It can recur and affect the heart. Clinically, it is characterized by migratory soreness, heaviness, and pain in the joints and muscles. It is an allergic disease. It is one of the main manifestations of rheumatic fever, and often starts with acute fever and joint pain.

Clinical manifestations

1. Pain

Joint pain is the most common symptom of rheumatism. Pain may occur in joints throughout the body, but pain in the limbs and trunk may cause lesions in the internal organs and nervous system.

2. Muscle pain

Muscles may also experience pain, and may also experience muscle weakness, elevated muscle enzymes, and myogenic damage, such as systemic lupus erythematosus, mixed connective tissue disease, and dermatomyositis.

3. Irregular fever

Before rheumatism appears, there will be irregular fever, no chills, and antibiotic treatment will be ineffective. At the same time, there will be a rapid erythrocyte sedimentation rate. Systemic lupus erythematosus, acute neutrophilic febrile dermatosis, adult Still's disease, and panniculitis can all have fever as the first symptom.

4. Skin and mucous membrane symptoms

Dermatomyositis, Sjögren's syndrome, Behcet's syndrome, and panniculitis may cause rash, oral ulcers, skin ulcers, reticular cyanosis, and eye symptoms.

5. Raynaud's sign

The fingertips will turn white when exposed to cold or when the mood changes, then turn purple, and finally turn red and be accompanied by numbness, pain, and severe skin ulcers, which can be seen in rheumatoid arthritis, systemic lupus erythematosus, and mixed connective tissue disease.
