I have low-grade fever mainly at night, along with fatigue, mild body pain, reduced appetite, and a feeling of coldness during fever episodes. I do not have cough, cold, bleeding, or rashes. The fever subsides in the morning after taking paracetamol. What could be the possible cause?
Low-grade fever occurring mainly at night, along with fatigue, mild body pain, reduced appetite, and chills, can happen due to several conditions, most commonly a viral infection, mild bacterial infection, weakness after illness, or inflammation somewhere in the body. In some cases, stress, poor sleep, anaemia, urinary infection, typhoid, tuberculosis, or other hidden infections may also cause evening or nighttime fever, especially if the symptoms continue for many days. Since you do not have cough, cold, bleeding, or rash, the cause may not be a simple seasonal flu, but it still needs proper observation. The fact that the fever improves after taking paracetamol is reassuring, but repeated fever should not be ignored if it continues for more than a few days. Make sure you take enough rest, drink plenty of fluids, eat light, nutritious meals, and avoid dehydration. Continue monitoring your temperature and note if the fever is increasing, becoming more frequent, or associated with new symptoms such as weight loss, severe weakness, burning during urination, stomach pain, swollen glands, or night sweats. If the fever persists for more than 4?5 days, it is advisable to consult a doctor for examination and basic tests, such as blood tests or urine tests, to identify the exact cause. Avoid taking antibiotics on your own without medical advice, as the treatment depends on the underlying reason for the fever. Early evaluation can help detect the problem and allow proper treatment before it becomes more serious.
