Hello,
Thanks for posting your query at DoctorSpring.com
Breast engorgement is not common as such until after childbirth.
Rarely it happens during pregnancy also, at 32 weeks, it MIGHT indicate a risk for preterm labour.
However, you have to put warm compresses on it, untreated breast engorgement might lead to breast abscess ( infection ).
Please stay well hydrated, dehydration itself predisposes to preterm labour.
Celestone ( steroid ) shots in itself is a factor that might have caused milk let down.
Do not worry, take rest.
Avoid stress, intercourse and any triggers such as jerky long distance travelling etc.
Do put the hot compresses and a tight breast bandage.
All the best
Please feel free to discuss further.
Regards.
