Can The Herpes Virus Eventually Turn Into HIV?

In the last two weeks I've had this uncomfortable pain in my groin area on the right side.  It isn't a bad pain it's as though something is pressing on other organs and I've been going to the toilet frequent but not every min.  When I do go to wee a min later I get the urge to go again but it's only like drops.  I am a person that can hold my wee for quit some time so I felt that it was strange me going to the toilet.  Also the feeling in my stomach feels like something a low like pushing down so I'm getting abit worried.  As I've said that the feeling I'm getting as if something pushing down I have look in the entrance of my Virgina and it looks like something is covering the entrance a roundish kind of shape also the skin feels thick and looks thick too. Before I notice the strange thing covering the virginal entrance I went to my Doctor she tested my urine with a stripe of paper, which she said I might have urine infection, but I'm not covinced as to why am I getting these pains in my stomach.

My doctor gave me Trimethoprim 200mg to take I didn't take them strait away as I wasn't convinced of the diaognosis but I've now started to take them one twice a day.

I am really getting worried more now of what's covering the entrance to my Virgina.  Can I have thiybriods or could my bladder or womb have fallen..please help?
