I'm quite ignorant on the matter, but what little I've been able to find online about vaginoplasty, don't you have to dilate like, twice a week, at least? I'm no doctor, but sounds like you may have pulled/tore something?

Might be good to just go to urgent care for them to take a look? Wouldn't they at least shrug, go "IDK, pulled muscle?" and give you muscle relaxants if that's what it is? Or to a gynecologist? Someone should probably take a look up in there or something.

I hope you find a medical professional that's actually professional, soon. Good luck.
