Hugs, Artie, I'm sorry... Would he be willing to test? Though if he's really ill, even if it's a bad cold (or flu), they may not want him to come in either.

In terms of taking an Uber if you take the sedative, I'd check with the policy of your doctor. I think some places might not allow that, though that might be after procedures with general anesthesia, to make sure you don't have a negative reaction to it. Though, if you'd already taken it and used an Uber to get there, I'm not really sure what they could do, aside from maybe make you wait at the office a certain amount of time to make sure the med has worn off.
