For some years I have constant nausea, never evolve to vomit, but are always present, most of the time are associated with empty stomach, but even after eating, the discomfort only decreases ... About 2 weeks ago, I feel pain in the outside of the trachea, just below the "Adam's apple" and along with these new symptoms, mild pain and discomfort in the region of the liver ... I have had bouts of burnout (somatosis), my doubt is, the physical part would be predominant or the psychological part would be the main , I must stop my activities and prioritize the diagnoses or this does not consider imminent risk and I can adjust it according to my possibility ... Thanks
