Hi,
I had also been told to "just bear with it" and "it gets better." But I had mastitis, a very painful breast infection. So DON'T decide to "bear with it" until you've seen a doctor. It's very likely you have one the conditions described in this forum (mastitis, thrush, engorgement, blocked ducts), but even if you don't, your doctor will be able to give you some tips to feel better. If your doctor doesn't, then you might have to do what I did: see your baby's pediatrician. I am currently breastfeeding my 2nd baby and doing just fine. For my 2nd pregnancy, I went with an OB/Gyn partly because of what happened with my first. Breastfeeding was horrible and my gen physician didn't know what to do. It was so bad that I was ready to quit and made an appt. with my baby's dr. to work on that. The pediatrician knew a lot about mastitis, why it occurs, how to get rid of it, ways to prevent it, etc. etc.
So I don't know if you have one of these conditions or not, but think about this: if breastfeeding is making you miserable, then you're not helping your baby. Baby rearing is so much more than feeding, it's also about changing, playing, cuddling, singing, and so much more. Good luck and let us all know what you find out. :->
