K.,
This may not help... but... I went through the same thing when my son was 11 months... I'm pretty sure I put a similar post to yours up here on Mamasource.
You have good suggestions regarding pain (ibuprofin, cool compress). I'd also put some lansinol on them to help them heal faster (the stuff you use when you have sore nipples at the beginning).
I will say, that I did keep nursing and he out grew it in a couple weeks. It was related to teething for him, so once his teeth came in, he stopped. Something that helped was to rock him until he was nearly sleeping, then once he was kind of out of it, slip my nipple in and let him nurse to sleep. My son never took a bottle either, so I felt I didn't have an option other than weaning, which I wasn't ready for (and he really wasn't either). We ended up nursing till 17 months.
Good luck, and good for you for nursing.
