I had pain for at least 4-5 weeks with my ds1 & dd2. Pushed through and it slowly got better. Pain would go all the way down to my toes. It was horrible! Just took a while for my nipples to get used to being sucked on and wet so many times a day. Are you using the lanisol cream? It was a lifesaver for me. Piled it on after every feed and it helped with the pain of breast pads touching my nipples too.
