Can Vaginal Discharge And Irritation With Burning, Itching And Swelling Be Treated?

I have a yellowish discharge in my vaginal area. It started to irritate the skin down there...so I rubbed on it a few times to relieve the irritation..however it started to burn and itch after a while. I notice that my vaginal labia was really swollen and red. But there is no smell at all....The discharge is very thick and mucus-like textured. What can I take to fix this?
