Patient's question:
The baby is 38 days old today. The arm received the BCG vaccine a month ago. A few days ago, the area where the vaccine was administered swelled up. Today, I noticed a lump under the armpit and some redness and swelling. What could be the reason?Doctor's answer:
Generally, after receiving the BCG vaccine, a lump may reappear locally, and inflammation may recur. It is not advisable to get the BCG vaccine if you have contact with water. If you notice lymph node enlargement on the same side of the armpit after receiving the BCG vaccine, and the lump is less than 1 cm, it is usually normal. If it is larger than 1 cm, you should return to the hospital for a thorough examination and treatment. The above is advice on the question "Why does my arm swell after getting the BCG vaccine?" I hope it helps you. Wishing you good health!
