Hello dear
Welcome to Health care magic family .
I have gone through your concern in depth .
@  Most common is infection of vagina ( from some type of bacteria ,   
     fungus  or  virus ) .
@  Recommendations  for  better  recovery 
-  Keep the genitals clean with antiseptic liquids .
-  Wear loose , clean , cotton under garments .
-  Drink plenty of liquids .
-  Tab. 
benadryl 2 times a day after meals .
-  
Miconazole ( 1%) cream for local application 3 times  a  day .
-  Systemic  antibiotics  and  anti fungal  requirements  need  consultation  
    in  person .
Hope this will help you for sure  .
Feel free to ask any future health related query anytime .
Thanks for evaluating my answer thoroughly .
