This is what Elaine Moore writes in her article about SJS:
While most patients with Sjogren's syndrome have symptoms limited to sicca syndrome, a subset of patients may develop extraglandular symptoms, that is, symptoms not related to the glands. These symptoms include fatigue, rash, cutaneous vasculitis, Raynaud's phenomenon, arthralgia (joint pain), myalgia (muscle pain), myositis (muscle inflammation), frank arthritis, and a particular form of erosive or aggressive osteoarthritis affecting the hands and feet.
