For a clogged milk duct, there are a few things you can try before consulting a doctor. Continue breastfeeding with the blocked breast, as the milk is still good. Make sure to empty the obstructed breast as much as possible. Start with the blocked breast and try different positions to help the milk flow easily. If it's too uncomfortable, you can apply ice for 10-15 minutes between feedings. You can also take acetaminophen or ibuprofen for pain relief. If the breast becomes increasingly red, painful, or warm despite these measures, it's important to seek medical advice.
