hi my daughter is 21,she has had an overian cyst when she was 14, and has had a burning sensation in the vaginal area for a few months now, she has been tested for urine infection, had ultra sound of kidney, uturous and overy and everything looks ok but last night she had maybe a drop of blood from her belly bottom (naval) and i took her to emergency and the doctor apprarently look inside the naval and said he could not see any thing wrong, I was not in the room with her and my daughter forgot to tell the doctor about the burning sensation , so I am vey worried what this is. I need to add they have tested her for all STDs and the test came back negative for everything but since she has already lost one overy due to the cyst , please adivse me .Thanks,
