Jock itch, technically known as tinea cruris, is a fungal infection of the groin which is not uncommon in human environments. Sweating may be an aggravating factor as well as rubbing of the skin. Our providers will perform an evaluation of a skin scraping in the office under a microscope and will sometimes culture the area as well. Topical and oral treatments are very effective. It is important to keep the area dry and use medicated powders such as ZeaSorb-AF Powder to prevent recurrence.
