Both Crohn's disease and Lupus are autoimmune diseases and yes, they can present together in a patient. May I suggest you review 'Rick Simpson Oil' as a modality of help.
Probiotics are not very useful for GERD. However, if you are hesitant about using the known medications, we know that Cannabis oil that you would make is very helpful and it has no side effects or medical interactions.
