Mastitis

I need some advice! I've got mastitis. My nipple is so sore and cracked and blistery that I've been only pumping on that side. I nurse baby on the non mastitis side then husband feeds him a bottle while I pump infected side. I know that nursing is supposed to help heal mastitis, but it hurts almost as bad as giving birth because my nipples are so sore. What do you ladies do to heal your nipples when it gets that painful? I want to nurse on it, and I try, but it's unbearable. Please no crazy judgement on our nursing.
