Feeling cold, with shivering, shaking, and a poor appetite, may suggest a fever or infection and should be taken seriously. Check your temperature, take a rest, and keep yourself warm while drinking plenty of fluids to stay hydrated. You can take a mild fever-reducing medicine if needed and try light, easy-to-digest food. If symptoms persist, worsen, or you feel very weak, seek medical care for proper evaluation and treatment.

Fever with feeling unwell is often due to a common infection and usually improves with rest and basic care. Take adequate rest, drink plenty of fluids, and use a mild fever reducing medicine if needed. Eat light food and keep yourself comfortable while monitoring your temperature. If the fever does not settle in a couple of days or you feel worse, it is better to consult a doctor for proper treatment.

A mild evening fever that lasted a few days and has now settled is less likely to be malaria or typhoid, as these usually cause persistent or higher fever with other symptoms. Since you are currently symptom-free, it may have been a simple viral infection that has resolved. There is no need for immediate testing if you feel well now. If the fever returns or you develop symptoms such as chills, body aches, or weakness, it would be sensible to get tested, as advised by a doctor.
