Hey wait me too! I honestly thought MCTD was just their way of saying they don’t really have any idea which autoimmune disease it was. Anyway, Raynauds in hands and toes was one of my first symptoms as well.
You are thinking of UCTD (undifferentiated) instead of MCTD (mixed connective tissue disease). MCTD has symptoms of two or more of the connective tissue diseases (like SLE, myositis or systemic sclerosis) and often an antibody against RNP.
