What should you know about pee chills?

Some people shiver briefly during or after urination because of an automatic nervous-system response to changing bladder pressure and body temperature. That short-lived sensation is different from repeated rigors or chills caused by illness.

Burning urine, urgency, frequent urination, cloudy or strong-smelling urine, lower abdominal discomfort, or blood can occur with a urinary tract infection. Fever, pain in the side or back, nausea, and chills can suggest infection involving the kidney. Chills may also accompany influenza, malaria, dengue fever, pneumonia, or a serious bloodstream infection, depending on the wider symptoms and exposure history.

Note whether the chills are brief or prolonged and check for fever if possible. Drink normally unless a clinician has given you a fluid restriction, and do not use leftover antibiotics. Arrange medical advice promptly when chills recur or occur with painful urination, fever, back pain, vomiting, or feeling unwell; urine testing may help identify the cause.

Seek emergency care for confusion, fainting, severe weakness, trouble breathing, very fast breathing, cold or clammy skin, severe flank pain, or a rapidly worsening illness. Fever with shaking chills and urinary symptoms also deserves same-day assessment, especially in a child, older adult, pregnant person, or someone with reduced immunity.

Ask whether urine testing is needed, whether the kidneys could be involved, which pain or fever medicines are suitable, and what changes should prompt urgent review.
