My 29 year old son has bee very sick for a month. He got a flu and respiratory like illness at holiday time. Unfortunately it has turned to something else. He doesn t have stomach pain. However he can t eat or drink without vomiting. He has had an endoscopy and they found a hiatal hernia. However the dr. said this is common and couldn t be causing this. He has lost 32 lbs in the past 3 weeks. He is living on the bathroom floor. I don t know what to do for him.
