Hi, What does your doctor say about this change in your abilities? If the doctor doesn't know you're having problems, call the office and ask to talk to the nurse. The doctors cannot help you if you don't tell them you're having trouble. If you told them months ago, tell them now that it's much worse. Lupus can cause lung problems in addition to heart problems. I read tonight that the involvement of these organ systems is unusual and they respond to treatment. Don't delay in talking with your doctor!
Good luck! Barbara
