If you have had a yeast infection before and can recognize the symptoms, and you aren't pregnant, you can treat yourself at home with medicines you can buy without a prescription. You can use an antifungal cream, or a suppository that you put into your vagina, or antifungal tablets that you swallow.
The term Veld, or Veldt, refers primarily (but not exclusively) to the wide open rural spaces of South Africa or southern Africa and in particular to certain flatter areas or districts covered in grass or low scrub.
You can see an example of a typical savanna here (http://www.csiro.au/images/mediaReleases/Burn1.jpg). The difference is that savanna trees tend to be much smaller and thus produce a much more incomplete canopy cover. Veldt is a generic Southern African word borrowed from the Flemish word for field.
