Congratulations on your little Izzie Belle finally making it here! Can't wait to see her pics! I breastfed my daughter until she was 2 and I completely understand the stinging shooting pain sensation when your first starting out! Be sure when she goes to latch on that she takes the entire areola and not just your nipple. Pinch your nipple as flat as possible and as she opens slide your entire nipple/areola in starting down and sliding upward so that her tongue stays under your nipple and bottom lip stays pursed out. Even if you have to remove it and do it a couple of times until she gets the entire thing in her mouth, its new to her too, but she will catch on. You will still feel slight pain, it just being a new sensation and new experience to your breasts, it will get better, I promise. Usually about 2 weeks in your nipples will become numb to the act of breasfeeding, you won't feel a thing! I promise! Just hang in there and don't give up, once they're numb, its like second nature! Congratulations again and best of luck!
