Patient's question:
The child received two types of flu vaccines at once: the flu vaccine and the type B flu vaccine. One arm became red and swollen with a hard lump.Test results: Will the child be okay if no tests or examinations are performed?
Doctor's answer:
If the child has developed redness, swelling, and hard lumps locally after vaccination, it could be due to the anesthetic causing local soft tissue effects or fluid accumulation. In your described situation, you can appropriately use cold compresses and massage, which should resolve on their own. In some cases, local bleeding may occur after the anesthetic. If you are still concerned, it is recommended to consult a doctor if necessary.
