Please help! My baby is breast feeding and when he feeds in the left breast I get a pain in my mid to upper back close to the spine. After he’s done it doesn’t hurt. And it doesn’t hurt when he’s sucking on the right breast.

I had a breast surgery on the left with a 2.5 inch scar going from the direction of my arm to my nipple and am wondering if that’s my issue. Also got an epidural didn’t know if that needed it up? If doesn’t change when I move positions. Has anybody had anything like this??
