my 1 yr old daughter has a quarter size raised red bump with a large white center on her upper leg that is progressively getting larger over the past 2 days. she got her 1yr immunizations a week ago i dont know if its related. she also had multiple red bumps on her back and belly for 2 days a couple days before she got this bump. I was wondering if she needs to be evaluated by her pediatrician.
Sorry for the troubles!  She absolutely needs to be evaluated.  The bump on the leg sounds likely to be a local infection, and it may need to be Chat Doctor.  No way to evaluate well without someone seeing it.  If the bump is in the same spot as the shot was given, then there is likely a local infection that may have arisen.  The rash on the back and belly could be related to the vaccine, but it depends on which shot(s) she got.  The varicella (chickenpox) vaccine may lead to a light rash.  That rash is not dangerous and just represents the body reacting to the shot, but the spot on the leg is not consistent with a normal vaccine reaction.
