I have given my child 6th week vaccine. it's been 3 days, the swelling is still there even after giving ice fermentation. The vaccine portion on the thigh got little hard.

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