Lump under armpit in baby

My 4 month old baby has a lump the size of a R 5 coin under his armpit. currently the paediatrician has referred us to a surgeon who has prescribed antibiotics for a week. the lump is apparently due to the swelling of a lymph node and occurs on the same arm where the BCG was given.

What is the cause of the lump and how should we treat it?

This is called a BCG abscess. This occurs very occasionally in infants who receive the BCG vaccine soon after birth in SA.The surgeon must NOT remove the affected lymph gland or attempt to drain any abscess that may be present. The swelling will disppear with time. It is important for your paediatrician to check your baby's immune status.
