Vaginal infection itching and redness.

I spent time in a Jacuzzi and also sat in wet swimsuit for more than 2 hours after swimming. This caused severe vaginal opening itching. I consulted one doc on practo on video and she gave me Candid V gel and Fluconazole 1 tablet at gap of three days It didn't subside in 3 days time. I visited another doctor in person and she gave me Doxycycline LB now for 10 days and Oldid V gel and vaginal soft gel suppository containing Clindamycin, Clotrimazole and Tinidazole. It's the second day of suppository n antibiotics. Today the second day I feel more itching upon insertion of the medicine. Yesterday when I applied the suppository for first time it didn't itch this much. Why won't the itching reduce. Even my perineal and inside my anus feels itchy now. Please advise doctors. I need this itching to stop asap. It's bothering me badly.
