Scleroderma's signs and symptoms vary from person to person, depending on which parts of the body are affected. Skin-related signs and symptoms Nearly everyone who has scleroderma experiences a hardening and tightening of the skin. The first parts of the body to be affected are usually the fingers, hands, feet and face. In some people, the skin thickening can also involve the forearms, upper arms, chest, abdomen, lower legs and thighs. Early symptoms may include swelling and itchiness. Affected skin can become lighter or darker in color and may look shiny because of the tightness. Some people also experience small red spots, called telangiectasia, on their hands and face. Calcium deposits can form under the skin, particularly at the fingertips, causing bumps that can be seen on X-rays. Raynaud's phenomenon Raynaud's phenomenon is common in scleroderma and occurs because of an inappropriate and exaggerated contraction of the small blood vessels in the fingers and toes in response to the cold or emotional distress. When this happens, the digits may turn white, blue or red, and feel painful or numb. Raynaud's phenomenon also can occur in people who don't have scleroderma. Digestive problems Scleroderma can affect any part of the digestive system, from the esophagus to the rectum. Depending on which parts of the digestive system are affected, signs and symptoms may include: 
Heartburn
Difficulty swallowing
Bloating
Diarrhea
Constipation
Fecal incontinence
 Heart and lung problems When scleroderma affects the heart or lungs, it can cause shortness of breath, decreased exercise tolerance and dizziness. Scleroderma can cause scarring in the lung tissues that may result in increasing shortness of breath over time. There are medications that may help slow the progression of this lung damage. Scleroderma can also cause the blood pressure to increase in the circulation that goes between the heart and the lungs. This is called pulmonary hypertension. In addition to shortness of breath, pulmonary hypertension can also cause excess fluid in the legs, feet and sometimes around the heart. When scleroderma affects the heart, heartbeats can become irregular. Heart failure may also occur in some people.
