I remember this exact pain with Lucas on the same side. When he latches and starts sucking, it burns like fire up my nipple, to my armpit and partway down my arm. The pain lasts about 10-15 seconds and the more he nurses the less it hurts. The nipple is also already agitated and hurts when it rubs against my bra. Ouch. I don't believe it's his latch because there is no pain whatsoever on the right side.
My initial thought is something getting clogged? I've tried feeding twice on that side before switching today even though it hurts. I figure getting it good and drained would be a good thing. It did bring done relief but the latch pain is still excrutiating.
I had a week and a half of excruciating pain on my left breast. Last Monday I pumped it out ONCE and it has been better ever since. My nipple was brutalized in that side too. I did lots of air time on it and finally got some prescription nipple cream for it. It even hurt when my towel brushed it after a bath! Take care!
Oh, one more thing, try different nursing positions. The football hold has been a life saver for the sore side!
You know, even when I was HIGHLY engorged in the beginning with past babies, I was never able to pump until closer to the 2 week mark. Anyway, I did have a stinging sensation every time Madelyn would latch on from about 3 days pp - and then it lasted for about a week. It was only when she first latched on (about 10-15 seconds).
Well, I always have pumping issues too. I can't pump unless the baby is actually in the room with me. If I hear the baby cry that will usually do the trick. The best thing is to nurse on one side and pump the other though... that's the best way to get a letdown!
It worked! I pumped while he ate and got about half an ounce. Sounds like nothing but that's a record. And when he switched to that side, the pain was much less horrible. It lasted a few feeds, it hurts again now so I will probably do it again. It almost feels like the clog is really close to the nipple.
