Just had letter from bath appointment, she said longstanding symptoms potentially consistent with uctd but low index of clinical suspicion. The longstanding nature of the symptoms is reassuring from a progression prospective. But I don't find that reassuring, I agree it's very unlikely I've got lupus as by now my kidneys would be affected but understood from reading that uctd did not cause organ damage (although skin is an organ and my photosensitivity is very bad).
I'll go for the calliscopothy test but if results are negative and no treatment/diagnoses made I won't be looking for medical help again.
