Patient's question:
The child is nine months old and has a hard lump after getting a vaccine. There's no redness or swelling, just a hard lump. It's been about ten days since the vaccine was administered. I'm wondering why the lump hasn't gone away yet? Could it be serious?Doctor's answer:
According to your description, the baby's condition may be due to a very small amount of peeling or possibly caused by an infection. You can use a warm towel for cold compress or potato slices, and it will gradually heal. If it's infected, you can apply some erythromycin ointment or povidone-iodine for sterilization.This is the advice for the question "Is it serious if there's a hard lump after a vaccine?" I hope it helps. Wishing you good health!
