Swollen hands and sausage-like fingers are common first symptoms of mixed connective tissue disease (MCTD). You may also be noticing that your hands become bluish or numb when you are cold or upset. This is called Raynaud's phenomenon and is another early symptom of MCTD. If you are experiencing these or other symptoms, such as muscle weakness or arthritis, you may want to talk to your doctor about a blood test to look for MCTD.
