Patient's question:
On March 19th, the baby received the third dose of the DTP vaccine. At the time, I didn't pay attention, and the doctor didn't mention using a towel for cold compress. Now, when the baby is about to get the second dose, I noticed a hard lump the size of a soybean in the muscle of the arm where the previous shot was given. It has been a month since the last shot. From the surface of the arm, the lump is not visible, nor is there any redness or swelling—it can only be felt inside the muscle. The baby doesn't cry or fuss when the lump is touched, and they are eating and sleeping normally. The second dose is scheduled for the day after tomorrow, and I'm very anxious.Past treatment history and effectiveness: None.
Kind of help needed:
1. Does this lump have any significance? Is it because the medicine wasn't fully absorbed?
2. What method can completely eliminate the lump? It has been a month—can it still be resolved?
3. Should a different arm be used for the second dose?
Doctor's answer:
This hard lump is not a big problem; it should be a stress response from the body after vaccination. Advice: There's no need to do anything about it. As the child grows, it will gradually fade and eventually form a round mark. Next time, you can switch to the other arm. This is the advice for the question "Baby has a hard lump in the arm after receiving the triple vaccine!" I hope it helps you. Wishing you good health!
