So, here's the update:
Saw the doctor, and he thinks what I have is the same as "hot-tub folliculitis", caused by clothes trapping sweat and bacteria against the skin, where on long day-rides, it all festers in hair follicles irritated by vibration and friction. Same advice as before: Shower frequently (check, right after ride), launder cycling clothes frequently (check and ditto), and keep the area well-exfoliated and free of hair (uh, check). Antibiotic ointments on the spots. (uh...gonna try something else, Doc). He says the turmeric likely won't cause any problems in reasonable doses and cited one poorly-controlled, low-sample study that indicated a possible link to kidney stone formation in those with a propensity for stones. I'm not taking any meds except my daily thyroid pill and no problem with interaction there. I'll be taking a standardized extract (95% Curcuminoids)450mg 3x daily. Not giving medical advice, just giving it a trial myself. I figure in three weeks I may know something as a result.
So, here's the plan, starting today:
- Change laundry soaps to another phosphate-free brand with no fragrance or additives. Extra rinse cycle.
- Rotate jerseys so they have a good chance to air after washing and before re-use in case any chlorine or soapy additives are remaining.
- Lay-in a new supply of Bikini Zone to use on my chest and to take with me for re-application mid-trip, since it seemed to work better than anything else.
- Start a trial of the turmeric supplements to see if that will help.
I can always switch back to a wool-blend jersey or to looser cycling clothes, but the current lycra stuff is so functional, I'd like to find another solution first. I've got about two months before my next big tour and a lot of long day rides in-between, so this will give me a chance to see if the new routine works. Yes, I'm doing a lot at once so I won't which thing helped. The thing is, I'm under some time constraints and it would be nice to get this rash cleaned up soonest, so I'm pulling all stops and tossing scientific method out the window. If I see improvements, I can always add things back one at a time. Thanks for the suggestions, everyone! I'll report back with results.
Best,
Dan.
