L., please do not feel like a wimp, the pain IS unbearable at times! My little guy couldn't latch on so I have been an exclusive pumper for seven months now. It seems that pumping produces pain that breast-feeding alone doesn't. I worked with a wonderful lactation consultant named Pat at Sparrow Hospital (don't know where you are), but I highly recommend contacting either a lactation consultant or Le Leche League, they can help.
What helped me was getting a bigger Phalange (sp?) and using copious amounts of lanolin. Also, unless you have an over-abundant milk supply DO NOT USE THE CABBAGE LEAVES!!! They will dry you up very quickly. Unless you want to stop breast feeding altogether, then they work great. On days when the pain was really bad I wouldn't wear my nursing bra, but wore my pregnancy tank with the self-bra built in. If you do that, make sure you wear nursing pads because the lanolin is hard to get out of cloth. Of course, I wear scrubs to work so no one could tell ;-)!
Hang in there, the pain does stop, eventually.
Hope this helps,
M.
