How Can I Cure a Rash in My Shorts?

Question: Warning — graphic material to follow!

When I ride farther than normal or sweat a lot, I get what I refer to as “diaper rash” or “swamp butt.” I think my sweat channels down the butt crack and pools near the bottom, causing the rash. I have tried A&D ointment and Bag Balm (both before and after rides) with no luck. Any ideas? — L.D.

Coach Fred Matheny Replies: This isn’t an unusual problem.

Sometimes the rash is caused not by sweat but by a skin reaction to the detergent you use to wash the shorts. Or, your washer may not be rinsing the shorts properly at the end of the wash cycle.

You might try changing detergents and not using too much, which also could result in less-than-thorough rinsing. A good bet is one of the “free” detergents that lacks dyes and perfumes. Tide and Cheer are two brands that offer this type.

Here are two additional things to try:

• Wear an absorbent shirt under your jersey to soak up sweat before it runs down your back and pools where the rash is occurring.
• Try a medicated powder like Mexana to help heal the rash. You can even put it on your skin and inside the shorts before riding.

If these tricks don’t work, check with your physician for a diagnosis and medication.
