<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am going on a six day bike tour day after tomorrow and have come down with a yeast infection and Im very worried about wearing bike shorts for 3-5 hours a day will worsen it. I have used a one day OTC miconazole suppository, but other than that, I dont know what else to do. Would a natural supplement, like garlic or yogurt be worth a try as well?  <response>: Hello, I suppose the yeast infection is on your groin? If thats the case you can use an antifungal cream fluconazole for example for a couple of weeks or for at least a few days after the yeast has completely recovered. Oral treatment has some benefits, and you can also use fluconazole by mouth for the same amount of time. Its better if a dermatologist diagnosed it though. I dont believe that natural supplements or any other non-pharmaceutical product would offer any help. Dont forget to keep the area clean and Chat Doctor. Avoid leaving your wet shorts on, after exercising! Kind Regards!
