Sore boob

Leeeilaaa • Mama to both 👸🏼🤴🏼

I currently still breastfeed my 2.5 yr old only for naptime and bedtime. Yesterday I woke up with my right boob sore and tender to the touch. Waking up today it is still bothering me. Any suggestions on what it could be from?

I had mastitis twice way earlier in breastfeeding with my daughter and it doesn’t quite feel like that.
