I hope you never need this information -- but I wanted to share that I had a very good experience with https://www.medinaction.com/service/house-call-doctors-in-paris/ I was able to have a doctor make a house call the same day and he was excellent. It saved my Paris vacation. Cost was reasonable.
Thank you for sharing.
