Swelling of the hand’s combined with Raynauds color changes and wrinkled fingers can be a sign of mixed connective tissue disease (MCTD), an overlap autoimmune disorder with features of lupus, scleroderma and polymyositis. This is characterized by high RNP antibodies in the blood as well as other autoimmune antibodies. A rheumatologist is the appropriate physician to consult to rule this out. I hope you get help with this. It’s very uncomfortable but can be treated to reduce symptoms.
