Dermatologist to recommend for coral injuries (scuba diving)

[Seasoul]

Hi,

Went scuba diving and got coral scratches on my hands.
I've seen a first dermatologist a couple of weeks ago but she only gave me an ointment and some regular cream. She sounded like she had no clue what she was treating exactly.

Can anyone recommend a dermatologist who would know about coral stings and injuries and give me the appropriate treatment ?

Many thanks for your help !
