i'am worried already about what happened to me.I'am also shy to see a doctor.

I have had this vagina ich on and off for a year. And i was thinking that this is just nothing serious."Thoughts" that it is just an ich that can be vanish,cure or not really serious. Until now, i was checking my vagina, i saw a small cut in the vulva area(outer part of vagina) like a blade cut.i was thinking maybe its because i scratched it so bad when i have the ich, the thing is i have it most of the time now.and what makes me worried is , why it didn't stop when i'm trying to put medicine on it already like vaginal ich cream? I have tried to check also from the internet, it closed to yeast infection but, i dont experience any white discharge.so I dont really know what's happening to me..

I'am worried because i dont want my partner to be infected if this thing is infectious.I hope you can help me with my problem..and advice what medicine is best for this ich.
