Thanks for the query to H.C.MM. Forum.
If I were your treating doctor for this vaginal itching
in area , I would come up with these possibilities , these includes.
1 Yeast infection , diagnosis can be confirmed by physical examination by a gynecologist .
2 May be a bacterial infection due to sex relation , diagnosis can be confirmed by vaginal swab examination .
3 May be due to allergy
either soap or some other allergen .
Change the soap , which you are now using ,instead use anti septic soap. Take care of personal hygiene .
In my opinion as pcos
is nothing to do this type of itching so consult a gynecologist and get his opinion.
Good luck. Dr. HET
