It took 2 weeks for mine to heal. It was so bad that my son threw up my blood and I freaked out and rushed him to the Dr. It gets better don't give up. It really is rewarding and creates such a bond once you get past this.
Also try and see if u have baby latched right thatay cause some of ur discomfort
There is also some nipple cream u can use safe for you and baby you can but it at walmart invthe baby section real cheap as well
Mine did the same thing so i would use either my breast milk or i bought this ointment idk what its called but its made by madela! I hope they get better soon
My nipples cracked so bad that they bled every time I fed my daughter I expressed for 2 days and bottle fed her I used lanoline and cabbage leaves on them in my bra I also put a little bit of my breast milk on them and let them air dry (lay down or youll leak everywhere) its soo painful but it does get better wishing u luck xx
