Patient's question:
What kinds of diseases can pediatric surgery treat, and which symptoms belong to pediatric internal medicine? How should I handle a hard lump on my baby's arm after getting a vaccine?Doctor's answer:
The hard lump at the injection site is likely an adverse reaction caused by the administration of the DTP vaccine. The most common adverse reactions to the DTP vaccine include redness, swelling, pain, and hardness at the injection site, as well as systemic symptoms such as fever. Local redness usually subsides within about a week, while the lump may take longer to resolve, often requiring one month or more.Children have weaker immune systems, making them more susceptible to conditions that might be treated by pediatric surgery. For parents, it's important not to panic. They should promptly take their child to a regular hospital for examination and treatment. Additionally, routine check-ups should be conducted for the child, and medications should be used under the guidance of a doctor.
