Frequently asked questions
Answers to the questions moms ask most about clogged ducts, mastitis, and breastfeeding.
1. What's the difference between a clogged duct and mastitis?
A clogged duct (also called plugged duct) is a hard, tender lump without fever. Mastitis is an infection involving fever, flu-like symptoms, and a wedge-shaped red area. Mastitis may require antibiotics — see a provider if you have a fever over 101°F (38.3°C).
2. Should I use heat or ice for a clogged duct?
The 2022 ABM guidelines recommend ice (cold therapy), not heat. Heat can increase inflammation and potentially push bacteria deeper. Use ice packs for 15–20 minutes at a time, especially after feeding or pumping.
3. Is massage good for a clogged duct?
Deep massage is no longer recommended. Vigorous massage can damage breast tissue and push bacteria deeper. Instead, use gentle hand expression or feed frequently on the affected side.
4. How long does a clogged duct last?
Most clogged ducts resolve within 24–48 hours with proper care (ice, rest, frequent feeding, gentle drainage). If it lasts more than 48–72 hours, or you develop a fever, see a healthcare provider or IBCLC.
5. What is the BAIT method?
BAIT stands for Breast rest, Anti-inflammatory medication (ibuprofen), Ice, and Time. It's the approach outlined in ABM Protocol #36 (2022) for managing clogged ducts and mastitis.
6. Can I prevent clogged ducts?
Some strategies: ensure a good latch, avoid tight clothing or underwire bras, feed or pump regularly (don't skip sessions), vary feeding positions, and address oversupply if you have it. Recurrent clogs may warrant an IBCLC consult.
7. Do I need to stop breastfeeding if I have mastitis?
No — continuing to breastfeed or pump is important for drainage and recovery. Mastitis is not a reason to wean. The milk remains safe for your baby.
8. When should I see a doctor?
Seek medical care if you have: fever over 101°F (38.3°C), flu-like symptoms, red streaks on the breast, severe pain, a lump that doesn't resolve in 48–72 hours, or pus/discharge from the nipple.
