Latch problems? One side only?

Chandra
My sweet angel is 5 days old. She is EBF and latches perfect on the right side. She never has had any issues at all with it. But the left side she just can't get a good latch on. I've tried everything. My left nipple is so sore and blistered and its excrushiating every time she nurses in the left side. She is constantly latching and unlatchung and gets extra air only on the left side. Anyone have tips????
