 [ Symptoms ] how can i heal a cut on my vagina  have no idea how i can get this but it is getting bigger and hurts more i do not have sex and am doing anything i can to keep clean i have read about having a salt bath but does this sting badly what else can i do [ Disease ] i have no way of evaluating the severity of this cut or fissure on your vagina or take a more detailed medical history to help narrow down the causes etc most mucosal tears will heal if you just leave them alone possible causes include irritation from clothing reactions to soapdetergents or even age related dryness i do not know your age or if you are having periods sanitary pads and tampons can also result in unintentional tears or irritation if this does not spontaneously heal you will need to be examined by your women is health care professional
