My 5 month old twins had their 4 month round of shots on Wednesday. I noticed on Thursday that my daughters cheeks seemed swollen, today is Monday, and they are still swollen and feel a little tight and hard. I think she is also teething so I'm not sure if it's the teeth or a bad reaction to one of the shots. The shots she had were Hep B, DTaP, Hib, IPV, and PCV 7. Any clues?
