Dear Madam , oms As i can gather from your information is that you are having symptoms characteristic of a few known connective tissue
diseases,but you may not fulfill all the required features of one connective tissue disorder. You may be havind a condition called MIXED CONNECTIVE TISSUE DISORDER. You may later on evolve into a single disease entity (eg - Lupus
) at a later stage of your disease. Since you are U1 RNP positive you have a greater chance of having a lung condition called INTERSTITIAL LUNG DISEASE.Kindy meet your rheumatologist
at the earliest and get yourself evaluated.Hope you find my answer useful. Take care.
