Boy timely thread!
I've developed some chafing and finally figured out today on my ride that it's the position of my seat so I'll have to make some adjustments and see how that works out for me.
Anyway I have this book which I really like and recommend it's by Gale Bernhardt and titled "The Female Cyclist, Gearing up a level". I'll share with you what she has to say on the subject, pages 283-285.
SADDLE SORES
Sores in the groin, upper leg and butt area can be a nuisance--or worse, force you to take time off the bike. The best teartment for saddle sores is preventing them. The most common sores include blocked or infected glands, which show up as lumps; pain in the pelvic bone area where your weight may be resting; and chafing problems.
PREVENTION
Be certain your bike is set up correctly by referring to Chapter 3. a saddle that is too high can cause the rider to reach too far for the pedals causing either pressure or chafing. A saddle that is too low doesn't allow the legs to support the body and puts excess pressures directily on your crotch--ouch!
To help prevent chafing, slather your genital area and upper thigh with a good emollient such as petroleum jelly. A relatively new product on the market is Sport Slick™, which combines the lubrication of Vaseline™ with anitfungal properties.
Wear padded cycling shorts without underwear. Cycling shorts are designed to reduced friction from seams and give you some padding to help reduce pressure on sensitive areas.
After the ride, get out of those dirty shorts. Good hygine is essential. Wash your crotch and don't wear those shorts again until they have been cleaned.
Don't suddenly increase weekly or daily mileage on the bike.
If you shave the upper leg and lower torso, a light application of antibiotic ointment after shaving may help prevent red spots and infected bumps.
Be certain the bike seat isn't tilted too far up or down, causing pressure or making you constantly push back in the saddle.
If problems persist, a different saddle may help, especially one with a soft or cutout area near the nose.
SELF TREATMENT
Soaking in comfortably hot bath water one to three times per day with help boils surface and drain.
Antibiotic ointments such as Neosporin™ aid in healing.
Moleskin with an area cut out around the sore may help keep pressure off the sore itself.
I hope this is useful to you gals I know the information has helped me a great deal over the years with saddle sores.
Happy pedaling!
Life is like a 10 speed bike, we all have gears we never use.
