My baby boy is now 2 months old, we took 45 days vaccine for baby, there was a swelling in my baby's left leg. I used thrombophob ointment for that. It's been more than 15 days now but still it is showing little swelling in his leg. Is there any solution for that? or will create any problem? One more doubt, while applying thrombophob ointment, we shouldn't apply over the injected area, we should apply around the injected area, is it true?
