It is true that doctors or hospitals will take the initiative to contact, because I am also in the medical industry now, and the network department of our hospital will also pay attention to some facts. If this happens, the consultant will take the initiative to contact, because this will not only help patients, but also improve the visibility of his hospital.
I suggest you ask what hospital they are from. It must be a regular big hospital, which can be found online. Don't trust any private clinic easily.
