#AskTheExpert my son is 2 yrs old and he's god some knot like thing behind his right ear...why does it happen??how to treat that thing?

A. Lipoma The common thing these days it is just a fat ball in the body which keeps moving but does not give any pain or anything but since without proper check up we cannot be sure about it once you get a check with your paediatrician a further checkup can only reveal correctly as to what it is it is just the Lipoma or something else
