Occam's Razor: The simplest explanation is most the likely one. Usually Systemic Sclerosis and/or limited Scleroderma is not characterized by arthritis like you describe. The typical biomarker is anti Scl-70 (anti-topoisomerase). Symptoms have to be put into a broader context and be characterized beyond elbow and forearm pain. This one you should see a rheumatologist about. Dermatology would be useful as well.
