Chronic Myofascial Pain

High anti RNP and negative ANA

I'm wondering if anyone understands my lab results. I went to my primary Doc for significant foot and hand pain with some swelling and redness. Xrays show osteoarthritis. Hisorically, I have chronic joint pain and myofascial pain syndrome for about 8 years now. But he also did labs. The labs showed a barely high anti RNP but a negative ANA. I had just completed 8 months of high dose anti inflammatory meds. The remaining labs were normal. I am currently waiting for my Rhuemy appointment. Frustrating! I'm 53 if it matters.

My primary indicated it maybe a connective tissue disorder. Anyone have an insight? Is it even possible given it was barely positive and the remainder is normal?
