I've had this for 7 years of more,periodic pain before period,burning pain during use of tampons and before the period extreme discomfort during and after sex and it's so bad I can't even wash up because contact with my finger or water could be so uncomfortable even urinating was stigmatising once I visited a doctor who would make me lay down put on his gloves and insert a finger in to the already irritated vagina and once more I went only to have the same treatment again and I stopped,tore out my prescription and buy over the counter only to have the same pain the next month of my cycle.Right now the pain is back and bad as ever,even though my period is done and over with sex with my partner is sweet and sour I'm glad now I have a name for it,a lasting solution will be sought next.
