youghurt!! the cultures in the youghurt counter the bugs and such in yeast infection (and by suggesting this, i dont mean you eat it!! you put a little bit on a tampon and up it goes (room temp so its not cold) eating it does help tho). this may not work for some however. you may need to get a medicated cream and or tablet.
Do you mean yeast infection?? Go to your local pharmacy & find Monistat or any yeast infection med. you may need to see your doctor to make sure this is what you have. I think they even have test kits for these types of things now, so you can determine exactly whats going on. (also pharmacy available)
You need to see the doctor to determine if it really is yeast. It could be bacterial which presents similar symptoms. Which yeast can be cured with over the counter creams, or homemade remedies, you might need antibiotics. Also your partner might need to be treated or the infection will bounce back and forth. See the doc.
Do not put any foreign items in your body it can cause an even bigger infection. See a doctor and go to the library there are many books on this topic. Don't forget your partner also has to be treated. Otherwise you will both keep on giving a repetitive gift you don't want.
