This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
You do have muscle and nerve pain along with weight loss.
So you have symptoms.
Now your ANA and RNP also came back positive.
Although not definitive, they do raise the question of a connective tissue disorder.
This can be MCTD, or even lupus.
Hence, clinical evaluation by a rheumatologist is required.
The diagnostic criteria for connective tissue diseases like lupus need to meet symptoms, clinical findings, and lab tests as well.
It was my pleasure to help you today.
