5Skin Bumps
CREST syndrome might cause calcinosis or tiny calcium deposits under the skin. These are hard spots that do not dissolve. Depending on the type of the condition, the size and shape of the growths can vary. Commonly affected areas include the fingers, knees, and elbows. You can feel and notice these deposits, which can become infected and tender sometimes. Keep in mind that calcinosis is a rare issue with many causes. Thus, consult your doctor to find out the possible triggers. [5]
