You have nausea or vomiting
You can have nausea or vomiting from severe pain, says Dr. Feuerstein, although its not a common symptom of a UTI. It can be a sign you have an upper UTI thats moved up into your kidneys and should be checked out.If you end up with a kidney infection youll have high back pain, too,” explains Dr. Feuerstein. Its called the costovertebral angle, which is at the base of the ribs.(Related: Natural Home Remedies for Nausea)
