I'm glad your husband likes his doctor. Imho, that's crucial. If I didn't already say it, please thank him for his service.
Thought you’d be interested in the follow up: Son-in-law got a bill from the VA - $15 co-pay for his VA emergency room visit. He’s not happy about it at all. Adds insult to injury (or abdominal pain, in this case). He’s said he’s going to some phone calls tomorrow. The money is nominal. It’s the principle.
