How to treat a recurrent vaginal itching and a burning sensation in a female?

Hello doctor,

I suffer from recurrent vaginal itching followed by a burning sensation while urinating for the past many days. When I take Itraconazole medicine. It gets fine but after a few days, it happens again. My vaginal discharge’s odor is weird even after I take care of my hygiene. My physical relationship with my husband is getting worse because of the vaginal itching. Please tell me which medicine should I take.

Please help.

Hello doctor,

Thanks for your reply.

I have also been suffering from PCOS for the past many years but my menstrual cycle from the past few months is normal. I am not obese and the periods last for five to seven days. But this month, I was having three days of spotting even after my period was over. My vaginal discharge is watery and mixed with a white substance. It smells like a rotten fish. The problem occurred after I became sexually active. Also after having sex, I take care of my hygiene, wash it with plain water and I urinate after sex.
