Dreading left boob feedings today😩

So I have what I think is a milk blister or some kind of sore from battling the latch with my little man.  Every time I get a good one with him he yanks off and goes for just the nip again😖.  Every left boob feeding has just been dreadful today.  Lots of Lansinoh between feedings!  I wish I could pump and bottle feed him just for that side, but he looked at me like I was trying to poison him last time I attempted to pump and bottle feed him😂.  Just some venting ladies.  Not many people in my day to day that I can openly discuss blistered nips with😂
