My question is for a friend....My friend suffers from extreme naseau, knotting in her stomach everytime she eats, diarrhea, extreme fatigue, and now numbness tingling in hands and feet. She has been through the ringer in testing...She doesn't have Crohs, Celiacs, IBS, and the list goes on...Is there any suggestions anyone could give me on what this could possibly be? I am so scared for her she is now down to 114 pds from over 200 pds in the past year...She is wasting away to nothing b/c she can't keep anything down!!! Please Help
