I'm hating breastfeeding DS right now

With DD it was the easiest thing I ever did, I could never really even feel her on there. The only issues we had were with lazy attachment when she turned 1, causing cracks and an infection, and then a bit of latching pain when I got pregnant.

Neither of those issues compare to this though. It's been different with DS from the start, I've had to be more careful with watching him latch and making sure he's on properly, it always seemed like he couldn't open his mouth wide enough to get enough in. Now I'm in pain every time, I'm dreading feeding him and I cringe through the first minute. This morning it brought tears to my eyes.

It used to be just the left so at least I could feed on the right and get some relief, but now they're both agony. The skin on the outside bottom is very thin, he's really worn it down. It's like he rubs it wrong with his tongue or gums or something. I'm putting on lansinoh and breastmilk but it almost feels pointless, they don't have enough time to heal between feeds anyway.

I'm wondering if it's a tongue tie, no health professional has said anything but DH and I can see it. I'm wondering if maybe he can't get his tongue out far enough and that's causing the rubbing. I'm not concerned with DS himself - he's definitely getting enough milk, output and growth is good. I just don't want to be in pain every time
