You have a positive ANA but you don't apparently have test results that make for a clear diagnosis. Many patients seeing rheumatolgy are monitored and watched but have to "wait" for a label. If I were you I would ask that some of those skin symptoms get biopsied.

The rheumatologist could give you Plaquenil (hydroxychloroquine) but there are (rare) risks. Other treatments would be steroids, anti-inflammatories, maybe immune suppressants. There are no magic answers in my experience and the treatments are rough.

Have you considered seeing a functional medicine/integrative medicine doctor or naturopath? They tend to look at the whole system and may have some suggestions. For instance, curcumin. Keep us posted!
