Low-grade (98.5°F to 99.9°F) evening fever with chills in the hands and legs is often seen in the early stage of a viral infection, such as the common cold or flu. It may also occur due to mild bacterial infection, dehydration, tiredness, or exposure to weather changes. In some cases, infections like dengue or malaria can also start with mild fever and chills, so it is important to observe other symptoms. At this stage, you should rest adequately and drink plenty of fluids such as water, soups, and oral rehydration solutions. Eat light, home-cooked meals, avoid overexertion, and monitor your temperature regularly. If you feel discomfort, body aches, or headache, you may take over-the-counter paracetamol as directed, but avoid unnecessary antibiotics. Watch for warning signs such as persistent fever beyond 2 to 3 days, increasing temperature, severe weakness, vomiting, rash, or breathlessness. If any of these occur or if your fever worsens, please consult a doctor for a proper examination to identify the exact cause and receive appropriate treatment.
