Capsaicin Cream on my Vagina

Exactly as the title says - I have capsaicin cream on (and possibly in) my vagina. My partner was cleaning and applying cream to my private area. He thought it was anti-fungal. It kicked in within a matter of seconds and I was crying screaming. I eased it ever so slightly by sitting in a bath of cold water for 10 minutes. I’m going to apply Sudocrem but I’m wondering if there’s anything else I can do to ease the pain. x
