I'd be really grateful for some help. I have been breastfeeding for almost a year and have just got a very painful right breast. It hurts underneath and is agony when she feeds from that side, which I am trying to do to ease the pain? I went to the doc this morning who diagnosed mastitis. I have a prescription to use if things get really bad. Any tried and tested cures would be welcomed or reasons why this has happened now when I have had no previous problems with this time or previous children's feeding.
