Low-grade fever may present symptoms and sensations such as body heat, dizziness and headache, weakness and fatigue, chills and cold intolerance, and loss of appetite.

1. Body heat: This is the main symptom. You may feel hot, especially in areas such as the forehead, neck, palms, and soles of the feet, where skin temperature is elevated.

2. Dizziness and headache: You may experience a feeling of heaviness, pressure, or throbbing pain in the head, with difficulty concentrating and a generally poor mental state.

3. Weakness and fatigue: There may be generalized muscle weakness, easy fatigue, reduced exercise tolerance, and a feeling of tiredness even after slight activity. Limbs may also feel sore.

4. Chills and cold intolerance: Although body temperature rises, you may feel cold, have cold hands and feet, and even experience shivering.

5. Loss of appetite: You may experience lack of appetite and disinterest in eating, even for foods you usually enjoy. This may be accompanied by symptoms of indigestion such as nausea and abdominal bloating.

If you experience persistent low-grade fever or other uncomfortable symptoms, it is recommended to seek timely medical consultation for diagnosis and treatment.
