call your doctor, there is supposed to be something you can use to help these even if it is magic mouthwash (something they give cancer patients who get mouth ulcers) rubbed on the sores. I would think anything you use orally on ulcers would help with these since they tend to have the same cause- lupus. I have only ever had 1 nasal ulcer and was miserable because I hadn't found here. You might try baby ambosol/oragel instead of adult strength. I wish I could help more but no clue what else to offer as a suggestion.
