31F: My partner 40M of 4 years has lived with constant pain in his back, spine and hip since a high school football injury. He’s an oral surgeon now and does a lot of leaning over people, which makes the pain worse for him. Almost every morning we've been together, he wakes up and the very first thing he says to me is that he didn't sleep well because his back is tight or his hip is aching. When he gets home from work, whenever we've flown on a plane or go on road trips or do ... almost anything, he is talking about the pain he is in and I don’t know what to say in response. I love him and care for him deeply, so it’s painful to know he’s in constant pain, but I can’t do anything about it. I offer to help in various ways and he always says no, and that I can't help him, so most of the time I just say "I'm sorry". When I say it, I genuinely mean it, but after 4 years of saying it multiple times a day, it's starting to sound like l'm dismissive/annoyed. What else can I say?
