unfortunately it's impossible to tell what the problem might be without a physical examination. difficulty urinating is not a symptom to be taken lightly. it could be caused by a urinary tract infection kidney infection or even a stone. any of these conditions could cause additional problems if not treated. the difficulty urinating also could contribute to the nausea and vomiting. if these symptoms don't clear up quickly i'd suggest you seek immediate medical treatment. hope this helps!
difficulty urinating nausea and vomiting. what the most likely problem. no fever
