My son is 11 and for the last year he gets sick once a week. It starts with him feels very tired, where he needs to go to bed. This lasts for 2-3 hours. Then pain sets in, in his stomach and he then vomits for about 6 hours (every 45 minutes). The next morning he is fine. This it torture to him but he s had an mri, ekg, eeg (sleepstudy), upper gi with biopsies, and all these tests are normal, along with is blood work. Any ideas? Please don t say cyclic vomiting because I m not a believer. He was fine a year ago. What should we ask the doctor tomorrow?
