Goog evening everyone. For almost two years now I m experiencing some strange crisis , about once a month. They usually last a all night : I have a severe stomach pain, and vomitting every other 30 or 40 minutes. I m also shivering and am really exhausted during this episodes, and can t eat or drink anything of course. And absolutely I can t lay down, or that cause another vomitting. Sometimes, I have a fever, and the crisis last longer and is worse. I ve seen several doctors, and get two echos and two MRI to search for stones, but nothing shows... If you have any clue that would really be helpfull to me. Thank you in advance.
