| It was somewhere between 2-3 weeks before it stopped hurting for me.
I remember in the hospital when they described it as 'toe curling' and that it would only last a few a days, to me it actually felt like having a piece of glass shoved through my nipple!
I can see why a lot of people give up as if they are telling people like me in hospital it only hurts for a few days and then two weeks down the line they are still in agony. If it hadn't been for copius amounts of nipple cream, shields, shells, pumping and paracetamol I don't think id of stuck it out. I could open a shop with the amount of stuff ive got here.
Well done for fighting through it, its hard work but worth it when you come through the other side. | 
still hurting but not for as long and not quiet as painful yayy!!
