Hi, Deb. Have you had discoid lesions before with your lupus? People who develop discoid lesions often get them on the ears and inside the ear canal. These aren't the same type of ulcers that occur in the mouth and nose because the skin lining your ear canals is different from the mucous membranes inside the mouth and nose - the lesions on and inside the ears are usually more rash-like, or may be scaly and hard. If they become infected it can create an ulcerated area. If these are the problem, your doctor should be able to see them by examining your ears with an otoscope. I don't have discoid lesions on my skin but do get them sometimes in my ears and my doctor usually prescribes steroid ear drops. But you definitrly want to find out if it is lupus or a yeast infection, because the steroids prescribed for lupus make yeast infections worse. Hope this helps.
