I have seen that some people here suffer from mouth ulcers, nose sores etc. I havent had that problem yet, (touch wood)
How long since you were dx with lupus? and are you taking any new medications that might be causing this? Sorry I'm not much help to you, but I hope someone comes along with more experience to shed more light on this for you.
Hope you feel better soon
