Pain when masterbating

Okay, basically, everytime I masterbate or even get wet in any way, I have burning and pain in my vagina and pain in my pelvis and stomach. Can anyone tell me why? I also don’t ever put anything inside of me. Only clitoral stimulation. If anyone has any advice I’d appreciate it!! (I’ve had abdominal and kidney ultrasounds and been tested for uti) could this be vulvodynia? Is that even a condition? And does this mean I should stop? Also whenever I put a tampon in it HURTS so bad that I went on bc to stop my period. (The patch)
