A deep nail cut that is still painful after 2 days can sometimes lead to a minor infection at the nail corner â called paronychia â especially if the area becomes red, swollen, or starts to discharge. Since you are breastfeeding, it is important to use only safe, doctor-recommended topical treatments. Keep the finger clean and dry, and avoid soaking it in water for now.
