Painful, inflamed vagina, pinching pain when getting up after sitting.

Just came on a few days ago. Cold water seems to soothe the area - moderately inflamed and irritated. Not really itchy I was wearing some polyester shorts with a high inseam that seemed to be an irritant (no undies) so I threw them out and then I applied by 3 x a week nightly pea sized dose esteriol cream for the dryness - and then the pain began. Sitz baths help.
The pain went away yesterday - I tried so many home remedies idk which one worked (kefir applied to whole genital area, baking soda sitz baths, coconut oil) I was so relieved and then it came back again today. Yeast infection? Not really itchy, no odor, no discharge I can see so it doesn't seem to be that. No sex or antibiotics.
Thanks for any advice!
