I'm so sorry, maddie. I was diagnosed with a metabolic problem years ago--not handling calcium oxalate--so I was given a list of foods to avoid. I also connected with the Vulvar Pain organization. (Be back in a bit with more details.) Okay, here you go:
Welcome to The VP (Vulvar Pain) Foundation
I don't know if it deals with internal pain, but it's worth a try. There would be a lot of supportive women there, too, who might have othery suggestions.
Please keep us informed. We definitely care.
i hope you feel better soon.
