DD is almost 3 weeks old and ebf, but I'm having issues with one breast. She feeds fine on the left side and tends to be satisfied quite quickly, but on my right breast she always seems to feed for longer and feeding is more uncomfortable, despite having latch checked and apparently fine.
Had a milk blister on right nipple just over a week ago. Managed to hand express and got the horrible little **er out, and feeding on that side got less painful again. It then came back a couple of days ago 
and after much massaging, feeding, heat, and even breaking the skin with a needle it seems to have gone again and feeding is now comfortable. However whilst it's got better, I'm now getting really engorged on that side at night, but fine during the day. DD is feeding roughly 2 hourly, and due to the most recent blister I had been trying to make sure she feeds from that side at every feed to stop it from coming back. During the day it's fine, and I can skip a feed with no issues, but at night I'm waking up after 2 hours and it hurts, and I'm also finding a painful hard area in breast (always same place) that I also had with both blisters.
I'm having to pump that side when I get up in the morning to relieve the discomfort. I don't mind so much as I'm trying to gradually build up a freezer stash so DH can give her the odd bottle when I am out and about, but I don't know if this is making the issue worse.
Any ideas though on how I can relieve this or whats going on? Im terrified of getting mastitis tbh. Once she's feeding it's fine until I've slept again for another couple of hours, and also during the day it's fine.
