As far as I understand the sicca symptoms can be caused by damage to the glands that secrete the fluids (tears, salive, sweat..) or to the nerve fibers that innervates these glands and regulate their activity.
The positive lip biopsy shows your salivary glands are affected so I guess it means that at least some of your symptoms are SS related and not SFN.
Although, maybe when the nerves that innervates a gland stop working then eventually it damage the gland itself.
