Vaginal Issues

Patient: I have recently been involved with a gentleman. Although we did not have sex, heavy touching did occur. A day or 2 after this happened I noticed that my vagina was rather sore. Now the feeling is worse and there is a gross yellowish discharge . Could it be a yeast infection? If so, how can I treat this quickly?

Symptoms: Yellow discharge from the vagina, burns when urinating,
