K.E.
RELAX my dear.
1. is all of your ducts letting milk out?
It sounds like a clogged duct.
start with a warm soak, massage then pump, pump, pump even if this is not a clogged duct this will stimulate your breast to make more. If the breast is clogged and not satisfying him fast enough he does not want to work, or wait for it.
STAY AWAY FROM SAGE this drys you up.
Seek a lactation consultant if this continues.
Good luck.
