text: She should go to her gynecologist right away. Some yeast infections need extra strength medication only a doctor can prescribe and she should have tests done because it may not be just a yeast infection. Is she taking antibiotics? This can bring on  a yeast infection. Also, a home remedy that my friend swears by is a plain yogurt douche. My friend says that rubbing it on the irritated skin, soothes it too. She should wear loose clothing and cotton panties. Yeast infections can occur due to stress. Make sure she is not too stressed.
