Nipple pain


I am 2 weeks PP and have been having nipple pain since first starting to breastfeed. I saw a lactation consultant both in the hospital after I gave birth and a few days after in the pediatricians office and they both said my baby has a good latch and I shouldn't be having any pain. I have extreme nipple pain while breastfeeding and randomly in between feedings also for a minute or so, (it comes and goes in between feedings.) Has anyone else had this happen to them? Any suggestions?
