Rheumatoid arthritis and mycoplasma infection

Arthritis is a general term for diseases associated with inflammation of the joints. Symptoms include local and systemic symptoms. Local symptoms include redness, swelling, tenderness, stiffness, and limited range of motion, and systemic symptoms include fever, general malaise, and weight loss.

Arthritis has various pathological conditions such as bacterial arthritis, tuberculous arthritis, rheumatoid arthritis, gout, pseudogout, psoriatic arthritis, and degenerative arthritis. Diagnosis and treatment differ depending on the condition.
