My baby has a lump inside his thigh after taking vaccine at 10weeks..it has been 6 days since vaccination i can feel the lump and it is painless..will it go away on its own?

A. after painful vaccines administration they can cause swelling in the limbs which can continue for more than two months also. z it does not require any treatment and should go away on its own. after vaccination immediately you should start applying ice as welzl as thrombophob gel to prevent such swellings from persisting
