I'm curious, how do you mean painful? I work in an office cube farm, and it's often noisy/chatty enough that I find it hard to concentrate without headphones or something. But I find most earbuds and cheap headphones uncomfortable to wear for more than half an hour or so, so I bought a big set of over-the-ear Bluetooth headphones that are great to wear all day long. Might be worth a try if that's your problem.
There is more attention given to the sounds of your family than your work colleagues. It's a completely different kind of distraction. And it's a little bit heartbreaking every time to say to a kid that you are busy right now.
I get increasing feeling of discomfort from wearing any type of headphones/earbuds for more than 3-4 hours a day and I've tried different kind of headphones/earbuds, invariably with the same result. It's probably an individual thing, I have plenty of friends who seem to wear something all day long...
