Question:

Will jock itch go away on its own?

Answer

There are several types of fungus that cause the red, itchy rash known as jock itch. Some may resolve on their own if the case is mild and the conditions that allow the fungus to grow are removed. However, it will likely be weeks, and the itch may drive you crazy while you are waiting. Most cases of jock itch will not go away on their own. It is better to use an anti-fungal medication and use it as directed. If it says to use it for two weeks, then use it for two full weeks, even if the obvious symptoms have disappeared. The problem is that the fungus buries itself deep into your skin, which is why you itch so badly. Using the medication for only a short time may eliminate the surface symptoms, but the fungus will still be present beneath the skin. The next time the conditions are right for growing, it will pop right back up.

The fungus that causes jock itch thrives in warm, moist areas. Thus, the way to battle the problem is to interrupt its growing cycle.

• When bathing, dry thoroughly before dressing. Since the same fungus that causes jock itch also causes athletes’ foot, dry your groin before you dry your feet, especially if you are showering in a public area. Otherwise, you will be introducing fungal spores right where you don’t want them.
• If at all possible, allow yourself to air-dry. If you’re at home, shave and attend to your toiletries before dressing. If you are in a more public area, loosely wrap a towel around your waist, then attend to a few things before dressing.
• Put on clean underwear after bathing. Otherwise, you will reintroduce the same spores to your skin that you just washed off. You should change your undergarments daily.
• Don’t wear the underwear you wore all day to bed. Change into something light and loose so your skin has a chance to dry out.
• If you are prone to getting jock itch, switch to looser, lighter-weight underwear that doesn’t trap moisture. Loose boxers tend to be better than cotton briefs in this case.
• If you have a case of jock itch around your waistband, move your waistband up or down to avoid the area for about two weeks to allow it to dry. Sometimes it helps not to wear anything below the waist at night while you are trying to get rid of a bad case of jock itch. The increased dryness helps resolve the problem faster.
• Powders can help absorb moisture; however, avoid those that contain cornstarch. The fungus that causes jock itch can feed on the nutrients in cornstarch.

You might be tempted to use a cortisone-based ointment to ease itching, but this is actually counterproductive. “Cortisone creams, tried by many patients, help fungus grow! The rash may get less red and itchy at first, but spreads out and recurs, itchier than ever, when the cortisone is stopped” [“Fungus Infections: Preventing Recurrence”, American Osteopathic College of Dermotology].
