That’s right. Jock itch. Let’s take a few minutes this morning to discuss this common affliction, shall we? I will warn you now that there are some graphic photos associated with this PSA, so if you have little ones around or are a bit squeamish, you might want to keep that in mind.
Defined, Jock itch (tinea cruris) is a funcal infection that affects the skin of the genitals, inner thighs, and buttocks. It causes an itchy, red, often ring-shaped rash. Jock itch gets its name because it is common in people who sweat a lot, and is also more likely to occur in people who are overweight. Although often uncomfortable and bothersome, jock itch usually isn’t serious.(source)
Symptoms of tinea cruris include: red, raised, scaly patches that may blister and ooze; patches often have sharply-defined edges; often redder around the outside with normal skin tone in the center; and abnormally dark or light skin (sometimes these changes are permanent). It usually stays around the creases of the upper thigh and does not involve the scrotum or penis. Jock itch may spread to the anus, causing anal itching and discomfort. (source)
Jock itch is caused by a type of fungus that can be spread from person to person, and is often caused by the same fungus that results in athlete’s foot. Here’s a tip from me to you: if you even SUSPECT that you have athlete’s foot, put your socks on BEFORE you put your undies on. Why? the fungus may rub off on your undies as your bare foot passes through the leg hole. Wearing socks during this process prevents the athlete’s foot fungus from coming into direct contact with your tightie whities (or boxers/briefs/loin cloth).
Here are some risk factors, according to the Mayo Clinic’s site: you are a man (man), wear tight underwear, are overweight, sweat heavily, have a weakened immune system, and have other skin conditions.
Seems like most guys I know fit into several of those categories (especially the first one, though…). Here, then, are the aforementioned images (and no, none of them are me; I just pulled them from google images):
