Got an appointment in less than a day. The nurse practitioner probably gave me a more thorough look over (absent labs) than my primary care would have. Gave me an inhaler prescription probably as much to do something other than tell me to just continue the OTC medication I was already taking.
Sure, in an ideal world, we'd probably have a next-day MD appointment for everyone. But there's a ton of stuff when an ER or physician isn't really called for.
