He'll Dr., My 15 months old baby is having lump on the site of vaccination. At 10th month she got her vaccine but the small lump raised after a month of vaccination. We ask our nearest pediac. and they said it is normal and it will go by the time. Recently I started applying ichthammol on her arm... I guess now my baby is having a little pain over there... she s trying to express how it hurts... though the Dr said it is normal, it made me worry... because the lump s really big and started paining also... pls give me solution.. here I attached the picture that shows the lump.
