SymptomsBy Mayo Clinic staff
Scleroderma's signs and symptoms vary, depending on which parts of your body are involved:
- Skin. Nearly everyone who has scleroderma experiences a hardening and tightening of patches of skin. These patches may be shaped like ovals or straight lines. The number, location and size of the patches vary by type of scleroderma. Skin can appear shiny because it's so tight, and movement of the affected area may be restricted.
- Fingers or toes. One of the earliest signs of scleroderma is an exaggerated response to cold temperatures or emotional distress, which can cause numbness, pain or color changes in the fingers or toes. Called Raynaud's phenomenon, this condition also occurs in people who don't have scleroderma.
- Digestive system. In addition to acid reflux, which can damage the section of esophagus nearest the stomach, some people with scleroderma may also have problems absorbing nutrients if their intestinal muscles aren't moving food properly through the intestines.
- Heart, lungs or kidneys. Rarely, scleroderma can affect the function of the heart, lungs or kidneys. These problems can become life-threatening.
