Jock itch on keto/carnivore?

Anyone experience severe fungal infection in the groin area? I get severe itch especially at night. So severe that it wakes me up at night, it's unbearable. I use an ati-fungal spray and cream for jock itch by Lotrimin 2 to 3 times a day. With no avail. After a workout my groin area smells of funk until I shower. I used to get bad BO when working out while fasted (omad or extended fast). I figured it was ketones turning into ammonia and coming out of my pores. Now that I eat before a workout, that BO subsided but now I have this issue of crotch funk and severe itch.
