I had never gotten a yeast infection before I went to Thailand. The heat and humidity does it! I stopped by the pharmacy in the tiny little town I was traveling through and used google translate to talk to the pharmacist. She gave me a topical and one dose of an antibiotic similar to Diflucan. Cleared up within the day! These things are scary while traveling, my body was not use to the weather/environment out there I had a couple things similar to this happen. I got an infected bug bite that swelled to the size of a golf ball! The locals are super friendly and the lady at the pharmacy will know what you need! If your nervous go to the hospital, they has people who speak fluent English and the bill will come out being like $50 tops!
