Please help!!!

I have this little problem with my vagina...I have tingling and a very slight feeling of soreness but it mostly is really dry and irritated. There are no bumps or anything like that. I know I don't have an STD. I think I may have a yeast infection but one of the symptoms of that is discharge. I don't have any discharge at all, in fact I'm actually dryer than normal. Does anyone think they know what this is? Thank you in advance!
