4. Troubleshooting
Following are some common breastfeeding related conditions�
If you experience any of these symptoms, contact a healthcare
professional or breastfeeding specialist�
Symptom Potential Causes
Engorgement Breasts are hard
and uncomfortable,
possibly with reddened
areas�
Milk not draining properly
from breast� Milk can
drain back into the tissue
causing areas to swell
and become tender�
Blocked/
Plugged Ducts
Area of breast will look
reddened and may be
tender to touch�
Milk not being drained
from a specific duct� The
area becomes ‘clogged’
up and milk is then
prevented from flowing�
Mastitis It often follows on from
engorgement but can
just occur suddenly�
The initial symptoms
are similar to flu –
fatigue, headache and
muscle aches, fever
and localized breast
tenderness� It can be
in one or even both
breasts and needs
immediate treatment�
A bacterial infection in
the breast tissue which
is often accompanied by
cracked nipples�
A Healthcare Professional or Breastfeeding Specialist can give you
guidance in breastfeeding your baby and using a breastpump� Their
