I went on an elimination diet last summer. I’m reacting to so many different things but a main thing is night shades. I can handle some lectins.  I suggest keeping a good journal for symptoms. It can take up to three days to feel a reaction. I leaned that from the dietician I saw. 

Wow! I’m so grateful to read this and I’ll try it. I’m a celiac since 1996. I’ve been so horribly sick this last year and doctors can’t figure it out. Constant muscle aches, basically all the symptoms you posted. Plus I can’t eat night shades and majority of lectins. It’s unbearable. Have an appointment with a GI celiac specialist but not until the end of May. Just had an upper endoscopy and colonoscopy and all they found were ulcers in my esophagus. I’m 52. 

Thanks @Scott Adams for this information. I also found some options as well. One of them is also offering gluten free seafood menu with alot of options as well: https://pappadeauxmenu.com/

HI, yes I get this reaction if I eat gluten by mistake or if I eat high fodmap foods as well.  I become nauseous, vomit then it hits the muscles, my legs sometimes give out.  It takes a while to feel "normal" again.  

The first step would be to re-examine your diet to see if hidden gluten is the cause. Eating out would be the number one source of contamination, even if restaurants offer gluten-free menus and options.
