Okay so my son's friend, male, 24-25 years old; he moved from the mid-west up to Seattle, Washington about four years ago. After around one year, he started to develop sporadic episodes of abdominal pain, watery diarrhea, nausea and vomiting, super heavy sweats, chest pain, pain during urination, chest pain, unintentional weight loss, and the eating/drinking of dairy products seems to cause gas and bloating. Crohn's disease has already been ruled out.
