Fever symptoms

A raised body temperature can occur with an infection, but how you feel matters too. Chills may happen as the temperature rises, while sweating can follow as it falls. You may notice low energy, reduced appetite, thirst, headache, muscle aches, or a faster heartbeat. Cough, sore throat, blocked nose, vomiting, diarrhoea, painful urination, or a rash can point toward the affected body system. Acute bronchitis and the common cold often present with respiratory symptoms, while cellulitis presents with a local area of painful, inflamed skin. The symptom pattern does not prove a particular condition.

Rest and take frequent drinks; small sips can be easier if you feel nauseated. Wear light, comfortable clothing and keep the room at a moderate temperature. If you use a thermometer, follow its instructions and record the reading with the time and your symptoms. Eat lightly as tolerated. Fever medicine may ease discomfort, but follow the package directions and ask a pharmacist about interactions, allergies, pregnancy, or liver and kidney problems. Do not give children medicines intended for adults.

Get urgent help for difficulty breathing, blue or grey lips, new confusion, collapse, a seizure, severe dehydration, a stiff neck, or a rapidly spreading rash. Seek medical advice promptly for severe headache, persistent vomiting, chest pain, severe abdominal pain, pain when urinating, or fever in a very young infant. Arrange a review when symptoms are worsening, last longer than expected, or affect someone who is pregnant, frail, or immunocompromised.

Tell your clinician when symptoms started, the highest reading you recorded, recent travel or sick contacts, new medicines, and any rash or breathing change. Ask what symptoms should prompt a return visit.
