in or near my vagina hole, there’s a whitish/cream colored thing, and i’m not sure what it is. it’s hard, and it’s sort of covering some of my vagina hole.
Could it be a cyst? https://www.mayoclinic.org/diseases-conditions/bartholin-cyst/symptoms-causes/syc-20369976 These can be just inside your vagina and sometimes are white? I agree that the best thing is to contact your doctor. They can perhaps do something online virtually or they may want to see you in person. Let us know what happens!
It's hard to tell from your description, but maybe lichen sclerosis could be described as "a whitish/cream colored thing." You might google it to see if it seems similar to what you have. The way to get it diagnosed for sure is to see your ob/gyn.
Oh, another thing that women sometimes have that could be described as "a whitish/cream colored thing" (if you mean in the vagina hole not outside it), is a lost tampon. Any chance of that?
