Have had Raynauds and Systemic Scleroderma (with fibrosing alveolitis) for about 20 years. One of my main problems is digital ulcers. However, now, I have a small sore on my elbow which is causing me lots of pain and discomfort. It's not much to look at but, boy, does it hurt just to rest on my elbow. Any suggestions as to how I can aid healing process?
