OK, back from the GP. He seems to think I have an underlying condition that has a rheumatological (sp?) base. He bases this on the fact that when I have taken prednisone in the past, my symptoms are greatly improved. However, as soon as the dosage ends, my symptoms return. He said based on this, it was highly unlikely it was MS, and he referred me to a rheumatologist.

Does anyone know of another rheumatological condition other than lupus that could cause PN?
