Got sick in May - pericarditis (3 times now) and it responds to Prednisone; peripheral neuropathy in right leg; tired all the time; have had Raynaud's for some years (Sjogren's, too.) Positive ANA, but other tests weren't definitive. "Butterfly Mask" (sometimes). Can this be something else? I'm on a lot of meds (Plaquenil, prednisone, methotrexate, neurontin,etc.) so my Rheumatologist is treating it as Lupus. Should I be looking for a second opinion?
