Painful bunion!

Go first to see your family doctor and take their advice.
If they refer you to a specialist it will be one with whom they are familiar and, if there is follow-up treatment, you are likely to get it from your family doctor so it is helpful that they know what is going on in advance.
In some situations you will get a higher refund from the mutuelle if you have been referred to a specialist by your family doctor - as I discovered to my cost when I went directly to a physiotherapist!
And, if you go directly to a specialist only to be told that it isn't a bunion, you are still going to get a specialist-sized bill.
