1) You are exquisitely sensitive to gluten and it is getting into your diet surreptitiously. It does this via food ingested, not due to utensils used, so I don't think you need to change the cutlery that you use to eat with.
2) The symptoms are not due to gluten at all but rather another condition may be at play. Typically nonulcer dyspepsia or visceral hypersensitivity, which is very common in the setting of fibromyalgia, are high on the list of possibilities.
A GI doctor can help sort this out.
