Systemic Sclerosis

More than 95% of people with SSc also have symptomatic Raynaud’s phenomenon (RP) attacks. RP attacks are caused by blood vessels in your hands and fingers that overreact to cold temperatures or stress. It can result in pain, numbness, tingling, discomfort, and discoloration of the fingers. People with RP attacks may also have trouble using their hands or have sores on their hands and fingers. Digital ischemic episodes are the most common indicator of vascular abnormalities in SSc and are a common feature of SSc. If you are 18+ and have a diagnosis of SSc, you may be elibable to participate in our EICOS 301 Clinical Research Study.
