Lyme arthritis

Lyme disease is an infection caused by the tick-borne bacterium Borrelia burgdorferil. If Lyme disease isn't treated, around 60 per cent of patients will develop symptoms similar to arthritis. These symptoms include inflammation and muscle pain, sometimes known as Lyme arthritis, and can normally be treated with antibiotics and disease-modifying anti-rheumatic drugs (DMARDs).
