Help! Itchy and sore "down there"


Hey everybody! I am looking for some advice, remedies anything! So, about 2 months ago I started feeling irritation and itchiness. I went to my gyno who gave me medicine for a yeast infection and some creams. It all went away and was fine. Then a few week later, it came back. I go back to my gyno who put me on broad spectrum antibiotics and medicine for a yeast. Again, it goes away. Now it is back....again... any ideas as to what may be causing this? I don't want to keep going on antibiotics if I don't need to. I am already using Summers <a href="">Eve</a> wash and Vagasil to help with the itch.

I appreciate any input!
