Fever with Chills and Body Pain: What to Know

Chills can happen as your body produces heat while its temperature is changing. Body aches may accompany the immune response. The pattern, how quickly symptoms began, your other symptoms, recent travel, and your medical history help a clinician decide what to do next.

Viral illnesses such as influenza can present with fever, chills, headache, tiredness, and widespread aches. Fever with shivering can also occur with a urinary tract infection or kidney infection, particularly when there is burning urine, frequent urination, pain in the side or back, or nausea.

In regions where these illnesses occur, malaria and dengue fever are also conditions clinicians may consider after relevant travel or mosquito exposure. A cough, chest discomfort, or breathlessness can point toward pneumonia. A rapidly worsening illness with confusion, severe weakness, or breathing difficulty needs urgent assessment because sepsis can develop from an infection.

Rest, drink fluids regularly, and check your temperature with a reliable thermometer if possible. Wear comfortable clothing and avoid heavy wrapping while feverish. Follow the label for any fever or pain medicine, and check with a pharmacist or clinician first if you have liver or kidney disease, a stomach ulcer, take blood-thinning medicine, or are pregnant.

Stay home from close contact while you feel unwell, wash your hands, and cover coughs. Arrange medical advice if the fever persists, returns after improving, or you cannot keep fluids down. Tell the clinician about recent travel, insect bites, new medicines, sick contacts, and any urinary, respiratory, skin, or abdominal symptoms.

Seek urgent medical care for trouble breathing, chest pain, blue or grey lips, new confusion, fainting, a seizure, a stiff neck, a severe headache, or a rapidly spreading rash. Get prompt advice for severe or localized abdominal pain, repeated vomiting, very little urine, marked drowsiness, or a sharp deterioration.

Do not wait for symptoms to become severe if you are pregnant, have a weakened immune system, or have a serious long-term condition. A child, older adult, or person who seems unusually difficult to wake may need assessment sooner. If malaria or dengue fever is possible because of travel or mosquito exposure, contact a clinician promptly and mention that exposure.

Ask: What infections or other causes fit my symptom pattern? Do I need an examination or tests? Which medicines are suitable with my existing conditions and medicines? What warning signs should make me seek urgent help? Could my recent travel or an insect bite change the assessment?
