For the past 10 years, I ve had a butterfly rash on my face, as well as a chest rash that appears about once or twice a month. When it appears, I also get an extreme intolerance to red sauces, wine, etc. I also get severe diarrhea when the rash appears. These rashes go away in about a week, along with the other symptoms. I ve had tons of bloodwork - doctors thought I had an auto immune disorder, or lupis, etc. All bloodwork came back fine. Please help.
