I have a same case as you, first use ice to cool your nipple, then you need to massage the breasts and nipples very hard. it will be very plainful.
No need to go to doctor. Waste time and money.
My nipples are same as your case, your nipples are 發炎. Massage your nipples as squeeze the milk out by hand, when you squeezing, you will feel like your nipples have pieces of hard things there. Tired to squeeze them very hard and then pump it.
Keep massage it and pump it, after three to four days, you will be return to normal. Your case is a very early stage so it will be easy to save. Take care!
