3 weeks ago my 1 year old daughter had shots, which caused a solid small bump inside in area where she had injection, what should i do? its been 3 wk

Lump from imm: There is a metal adjuvant ( a component of the vaccine that brings it all together) that can be left in the fat tissue on the way down to the muscle. This can leave a little lump in the leg. It usually resolves over a couple of months and nothing to worry about.

It's okay: These bumps are very normal after getting shots. They can take a while to resolve (couple of months even) but they do eventually go away. Be patient
