HealthBoards - Desperately need help!!!!

I recently finished my period, and few days later I started getting tingling feeling in my vagina. It's all over and it's in the anus too. Today I feel it in my legs. My vagina does look a lil inflamed. I had unprotected sex in mid November. I don't know what this could be. I have been checked for uti and it was negative. I have been tested for std and its negative but not for herpes. Everywhere I read they say it's a sign of herpes. I don't know what to believe. I get this unusual feeling after I pee. During unrination it burn occasionally. The tingly feeling is the towards the buttocks as well.
Please help me. Is this herpes? I haven't had any outbreaks so far.
