#asktheexperts hard lump is formed after vaccination

A. Hello! It is very common for a firm lump to form at the injection site. It is a very localised reaction and it often results on his own within few weeks or months. Just monitor for any symptoms like the area has becoming red or painful, there is an increase in the size of the lump. There is a pass formation or your child is having fever. Inform your doctor about the symptoms and seek advice.
