Back pain with a feeling of wanting to vomit may be related to the following etiologies: First, it may be caused by serious trauma to the back. For example, serious soft tissue contusions or fractures in the back, or contusions inside the chest, pneumothorax, hemothorax or other injuries may lead to very severe pain in the back, and due to the pain is too intense, which leads to irritation of the patient’s digestive tract, then there will be nausea; second, may be due to a series of visceral-related pathologies. For example, when patients have acute myocardial infarction, angina pectoris, aortic coarctation, pancreatitis and other diseases, the above-mentioned lesions may lead to severe back pain and produce nausea and vomiting symptoms; third, due to severe cervical spondylosis. If the patient suffers from very serious cervical spondylosis, it may lead to fasciitis in the back of the shoulder due to the lesion of the cervical spine, which in turn leads to pain here, and due to the stimulation of sympathetic nerves or too much pain stimulation, which leads to the above-mentioned lesion in the gastrointestinal tract, and then produces nausea and vomiting.
