My daughter who is four yrs old was given preschool vaccination of DT, MMR and chicken pox five days back, two of the injections were given in the arms and one in the front of thigh, intially she was complaining of very much pain and was limping very much , the pain is now less and she is some what still favouring her leg, today I noticed that she has a lump at the injection site which is painful on touch is it normal?
