Breast feeding troubles

I'm a first time mom, Today my baby is a week old and breadtfeeding has become excruciating. I thought at first it was a bad latch, but my lactation consultant and hus pediatrician bitg say we have a perfect latch.

Whenever I go to feed him it feels like slmone sticking needles into my nipples and my entire breast itches and burns. I end up in tesrs every time and I've tried to push through it but I can't. Has anyone ekse experienced this??
