Bump under immunization site

[deleted account] ( 8 moms have responded )

My daughter got her 6-month shots (late) April 14. There were two - one in each thigh. Her right thigh now has a pea-size lump beneath the site of the injection. The PHN said this is a "normal side-effect" that I just need to keep my eye on.

Anyone else experience this? Should I be alarmed?

No it is still there. It didn't appear until a few days (a week, maybe?) after the shot. It doesn't sit right with me. She said only if it gets bigger should I see a doctor. But what does it mean if it's getting bigger?

My son had a bump in his thigh too after the immunization but it went away within a few days. Has yours gone away?

Seth had a bump too. He only had it on 1 thigh, the other one was fine. It lasted for over a week, but finally went away. It never seemed to bother him.

my daughter is 6months and just got her 6months shots last week. last week her leg was fine and now she has a pea-size lump in her leg. im calling the doctor tomorrow cause it bothers me. i have rubbed it and it doesnt seem to bother her but ive never seen anything like this before. my son never had it before so im kinda concerned that its appearing on my daughter..

I have 4 children and they have had bumps after shots - sometimes not appearing right away, perfectly normal, but it is a little scary. Use a permanent magic marker and circle the bump. You will know it is bigger if it goes outside the marked area.
