Hi,
Welcome to ehealthforum,
Each time you get treated, your partner should be treated simultaneously and you should avoid having intercourse while being on treatment. If the infection is persistent or recurrent, consider requesting your treating doctor/gynecologist to get a culture sensitivity test done on the discharge to look for causative agent and the best suited medication to eradicate the infection. Drink plenty of water. Keep area clean. Use loose cotton undergarments. Avoid use of harsh soap, perfumes, deodorants, any chemical use. Keep diet healthy and eliminate refined sugars from diet along with caffeinated and carbonated beverages.
Take care.
