UCTD is undifferentiated connective tissue disease and is a typical diagnosis when someone does not have a clearly definable set of labs and symptoms but exhibits symptoms of several AI diseases. UCTD often morphs into something else over time.
I have MCTD (mixed connective tissue disease) which is lupus, scleroderma, and polymyositis. Many AI diseases are difficult to diagnose and it can take a long time to get a definitive diagnosis.
Sounds like you might have doctors who are not that experienced so I suggest you interview doctors and/or clinics to find ones who have lots of experience with AI diseases. Even if you get a diagnosis these diseases manifest differently in each and every case and no doctor can accurately predict how yours will evolve or how you will react to treatment. Frustrating but a fact of life.
Mixed connective tissue disease (systemic lupus, scleroderma, polymyositis), Raynauds phenomena, Hypertension, Barrett's esophagus.
