A continuous high fever with severe body pain for three days usually points to an infection that requires proper evaluation rather than just symptom relief. Keep yourself well hydrated with frequent sips of water or other oral fluids, take light meals to help your body cope better, and rest as much as possible to support recovery. You can continue simple cooling measures, such as a lukewarm sponge, to ease discomfort, and avoid self-medicating beyond what has been advised, as the cause is still unclear. Try to monitor your temperature and overall condition throughout the day. If the fever remains high or if you feel increasing weakness, it needs attention. Consult a doctor promptly for proper tests and targeted treatment.

A week-long fever is often due to an infection that has not fully resolved and requires proper attention. Keep yourself well hydrated with water or oral fluids and take light, easy-to-digest food so your body can recover, and get enough rest to support healing. Check your temperature at regular intervals to track the pattern, and avoid self-starting medicines without knowing the cause. Maintain good hygiene and avoid exposure to infections, as your body is already weak. If you develop chills, body pain, weakness, or the fever keeps returning, it may need further evaluation. Consult a doctor to determine the cause and guide appropriate treatment.
