I thought stupid things like clogged ducts were behind me after 9 months of breastfeeding!

Last week i had a clogged duct and it took a few days of massaging and hot showers for my breast to go back to normal. I thought it was fine but i noticed a lump towards the nipple so i massaged it during feedings. The next day my nipple was in sooo much pain! It's been a few days now and i cringe every time LO nurses. It will get a little better once she starts nursing but it's still painful by the time she's done.

Any insight on what it could be, and whether it will just go away on its own?
