Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
You had Crohn's disease, and under controle. Recently you had stomach disturbance with green stools, stomach cramping etc.
If you are strictly avoiding the gluten
containing foods like wheat, barley, malt ,triticale, and oats, it is definitely not crohns .
It appears to be the amoebic colitis
, an infection by an protozoa. I advise you to consult a physician for diagnosis and treatment.
Don't worry you will be fine in no time with treatment.
