Patient's question:
Dear Experts:Hello!
My child is 10 years old. Last Monday, he had a sore throat with a fever that reached a high of 37.8°C (armpit). After taking two doses of traditional Chinese medicine, his condition improved, and we didn’t pay much attention. However, over the past two days, we noticed low-grade fever (around 37.3°C) again, along with a sore throat and swollen lymph nodes in his neck. My child had tuberculosis before he was 3 years old. Could this be related to tuberculosis, or is there another cause? Thank you! Thank you!

First follow-up question: Dear Experts:
Doctor's answer:
Multiple diseases can cause low-grade fever. Fever is a symptom, and conditions such as rheumatism, tuberculosis, chronic inflammation, and weakened immunity can lead to persistent low-grade fever. Long-term psychological stress and emotional instability can also disrupt the body's temperature regulation center, resulting in unexplained persistent low-grade fever. Any issue in the body's systems can potentially cause persistent low-grade fever. Taking antipyretics for low-grade fever patients is not beneficial for treating the underlying disease. Misuse of antipyretics can also lead to risks such as leukopenia and aplastic anemia. Antipyretics should only be considered when the body temperature is above 38°C.
