Hi, Im Experience Burning Sensation With Mild Itching In And

Hi,
Im experience burning sensation with mild itching in and around my vulva area and after visiting 2 gynecologist i was asked to use cansoft cl vaginal suppositories with oral fluconzole tablets but for some reason after inserting cansoft cl my vulva area is burning more and becomes dry, what could be the cause I'm extremely worried please help me

I had used cansoft cl 3 years ago and that time it didn't cause me any irritation or burning but I don't understand why it is burning now and its the 3rd time I'm prescribed and its burning too much
