What Causes Persistent Pain In Clitoris?

Hi,
I've been experiencing pain in my clitoris for months now, about 5. It started when I was prescribed amoxicillan for about 2 weeks. After the course, I noticed what seemed like a yeast infection, so I treated it using antifungal medication, but there was no improvement. I also got put onto birth control, which after about 3 weeks on it, I began noticing extreme soreness and tenderness in my clitoris. I tried different kinds of birth control, but there was no improvement, so I went off it. I also tried more antifungal medications, and all failed. I got a swab dine and blood taken, but it all came back clean. The discharge I have sits around my clitoris area and it's white and flaky, and seems to be coming out of my vagina. The clitoris is extremely tender especially after its touched. There is an unpleasant odour and it's itchy. The clitoris is bulging and it feels almost like it's got a bump underneath it. I'm at my wits end here and nothing is working. I'm 16 btw
