Hello girls, help me… We've been at it for 4 days, when the baby sucks…

Hello girls, help me… We've been at it for 4 days, when the baby sucks on the breast very painful, after the pain remains ….. and so every day, the nipples cracked, I smear Bepanthen cream and Purlan doesn't help…. I'm applying correctly… the baby can suck for an hour, all that time the pain…. How can I get the wounds in the nipples healed as soon as possible???? On the photo is the left breast, I don't give it to the baby (I pump but milk still flows
