Welcome to the forum.
It sound like you have some autoimmune issues, which usually starts because of a leaky gut. Undigested proteins then leak through gut causing an autoimmune reaction like arthritis.
One of the causes of a leaky gut is gluten, so it's a good think you are going wheat free.
I'm not a bread person myself, but I think that most people who make breads are going with almond flour, which does not need yeast.
