Infected stitches

I gave birth to my gorgeous daughter two weeks ago and my stitches have been in absolute agony ever since. Today I went to my Dr and was told they are infected, and that the stitches aren't healing and I have to get re-stitched after the infection has cleared - he gave me antibiotics for this. Has anyone else experienced this and know how to soothe things? I'm so sore and it's been such a miserable first two weeks with my baby girl! :(
