At first and only during the first few complaints about an ailment...like a tooth or sore hip/shoulder, etc. I'll really be concerned and suggest to him that he should go see a doctor.
If after some time he still does not go and is still complaining about his pain, I'll ask him if he made a doctor appointment to get the problem taken care of. Of course he'll say, "NO". Then I'll say, then if you're not going to get it checked out, I don't want to hear it. Either do something about it, or be quiet.
I don't mean to be so harsh, but, if he's not going to be responsible enough to focus on his health, then I don't feel sorry for him. I LOVE my husband dearly! I really do, but, I DO NOT have control over him or make his decisions for him. He's so stubborn and hopefully one day, he'll learn.
