Hi, I had gone through your question and understand your concerns. Nausea is not a common symptom of cervical spondylitis, in general is not connected with this condition, so I suggest you to consult your primary care Doctor and to discus about other conditions that may cause nausea like gastric problems ( gastritis, ulcer, esophagitis) or middle ear diseases and the examinations needed to properly diagnose your problem. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
