Patient's question:
When getting the hepatitis B vaccine, a small bump appeared. At first, I didn't pay much attention, but later it developed into a lump. Now it seems like a layer of skin has peeled off, revealing red and tender flesh underneath. It's soft, and it looks like there's pus inside, but it's hard to see clearly. The baby hasn't shown any special reactions.What kind of assistance is needed: What should be done? Is it necessary to go to the hospital?
Doctor's answer:
1. Vaccination, this is normal. Local anesthetic may reappear as red or dark red, lentil-sized small nodules, followed by redness and swelling. The center of the nodules gradually forms a small pustule and breaks open spontaneously, with a diameter not exceeding 0.5 cm. 2 to 3 weeks later, the wound forms a scab, which gradually turns yellow and peels off, leaving a permanent scar locally, also known as "kashaba."Advice:
2. For any vaccine, if the vaccination technique is not standard, this is abnormal. If the anesthetic site is not deep enough, within the anesthetized fat, it may cause the vaccine to metabolize slowly in the fat, forming lentil-sized bumps.
Solution:
You can use hot or cold compresses for about 1 month. Additionally, cutting potatoes into thin slices and applying them directly to the area while the baby is asleep can also help with metabolism.
