My 6 month old baby has fever?

She got her 3rd set shots yesterday,when we got home she was screaming in pain her leg was swollen,i gave her pain reliever then she slept through the night,this morning she has fever,and im so worried,i gave her paracetamol every 4 hours and i always check up on her.My heart is really broken to see her like this.I hope can help her besides holding her and rocking her to sleep.Moms what did you do to soothe your children after vaccinated? my my heart cries out.. = (
