Hello and hope you are doing well.
It could be a fungal infection that is causing the itching. So, please ask him to use OTC antifungal medications to be applied locally.
Hope this helped and do keep us posted.
I wld tell him to powder up before work instead of using cream. I think u'd want it dry there. Idk if it works on the crotch but my daddy used to swear by gold bond. Cream at night wen hes not sweating tho.
Hi sweenyB42 and welcome to the forum.
1. 100% cotton loose fitting underwear.
2 . Use of pure zinc oxide cream (non-scented) daily or as needed.
3. Frequent washing with mild hypoallergenic soap . Rinse well and dry.
Hope this helps,
Niko
