Jock itch or something else Help please

Hi so for the last week I’ve had this intense itching in my groin, after some research i discovered that apparently its jock itch from the way it looks and how its shaped, anyways today i noticed my labia incredibly inflamed like ive never seen. Does jock itch cause this? I just started using jock itch medication and i think it makes it feel better but im really concerned as to why my labia is inflammed, i want to to my obgyn but im embarrassed because what if its an std im really embarrassed and nervous

Thank u
