Lady problems 😑

I have burning in my outter labia area. Pretty near the vaginal canal actually. It's not red and it doesn't burn when I pee. It's burning and not exactly itchy. Not really painful except sometimes when I wake up. Cold water seems to help. 
No sex in a while and I do masturbate but I always use clean hands and toys. 
I did use a summers <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> wipe a week ago and I'm wondering if that had anything to do with this?Â
