Hello. My dad has recently been having many problems. He was recently diagnosed with Lupus and is on medications to suppress it. It has been suppressing it pretty good. In the mean time, his lungs have been diagnosed with Fibrosis and have lost 80% of their functionality. On meds he is doing better now. However he seems to be having coughing attacks randomly every few days. Once in awhile he will all of a sudden stop breathing in. HE will only be able to breathe out. It lasts anywhere from 5 seconds to 30 seconds. Then all is normal. Sometimes is happens while drinking things and other times just after coughing. It seems like Laryngospasm but could it be related to the Lupus or is this something new on its own. It has been happening randomly for about 4 years now and no doctor can figure it out. They just put him on Allergy meds but they dont seems to help... Any ideas? What would be the next steps if any? Also is it life threatening?
