I think he's 'saying' the thought of the Dr's appointment and the implications that may follow, is too much stress with the addition of the work stress.
Without hitting any panic buttons, so to speak, perhaps if you can remain calm and talk with him after some stress abates, that this would ease your stress (for him) to go to, not to mention it's preferable going in on your own 2 feet than by ambulance, perhaps he will try to do it for you more than himself.
