I have mastisis

My LO ripped a tear in my nipple so I went to see my LC and she recommended I pump that side for 2 days and continue to nurse on the other side. Then this morning I woke up with a 102 degree temp and flu like symptoms (dizzy, hot and cold flashes, shakes, aches) so called my OB and she ordered some antibiotics. Anyone have any experience with this? How long does it last? When will I start to feel better? Any tips on massage, heat, nursing? TIA
