Pumping issues !!

Soooo my right nipple has recently gotten cracked and it’s taking long to heal so in turn I pump on a lower setting which doesn’t quite get the same stream as my original setting. Now my right breast is more (noticeably) fuller than my left. What can I do to “level” my boobs out!! I’ve been messaging before my pumps and doing the warm showers and massaging while pumping but my right boob is still fuller.
