There are antivirial medicines out there. They are low cost and the big ones don't have any long term side effects. However, they don't kill off Herpes because of how the virus works.
I can understand sleepless nights and so forth. You aren't alone in being fearful. Low risk doesn't mean no risk it just means its a numbers game. The thing to remember is that unless these people had active coldsores then chances are even further. You don't know these individuals have HSV and nothing to support that they do. Is there a chance? Sure. Is there a risk? Sure. But its low. In the future get a condom on and use a condom. Or wait until you meet someone to have sex with and eliminate the need for concern.
Not everything that goes on down there is herpes. I can give you a perfect walking story of it. Review this thread:
This story is of a guy who recently went through an encounter that put him at risk. 11 weeks later (we typically recommend the 12-16 mark for testing) he tested. Guess what the test came back as? You got it... Negative. He had varying symptoms and so forth for days. If you want another story I am one of those that even here I struggle with beating Herpes out of my own head. Kind of werid huh? The guy who can answer questions he himself has his own fear...
I had unprotected oral sex. This again is a low risk activity. I freaked out (it was just like you a stupid dumb brainless thinking with the wrong head move I could make) it has put a lot into jepoardy in my life. Now that I go back and thinking about it I go.... Wow why the hell did I do that? I am now week 10 of my journey in fear. In the first 4 weeks of things I saw 2 doctors who told me I had a fungal infection. I got a herpes test at 2 weeks. Then in the next 4 weeks I saw 1 Nurse at the STD clinic (2 times because I was scared) 2 doctors, 1 Dermatolgist, and check myself daily both mouth and genitals. At 2 weeks testing I came back negative for both HSV types. At 9 weeks (9 weeks 2 days to be exact) I was scared crapless because the nurse practionier who was taking care of my aunt said I had a cold sore. She did a HSV test. I don't think I have EVER been that scared to go to a doctors office before in my life. The doctor asked me about Herpes and why I was scared and its nothing major it is nothing to be afraid of so I figured he was preparing me for the news of a positive test. When he was done he had printed off my lab work handed it to me knowing that I have done my fair extensive research into this and told me to interpret my own results. Looking at them I was and am still currently testing negative. So what are my chances? Just about the same as yours and that is low. In the time I have been dealing with doctors my dermatolgist says it is a fungal infection. I can't argue with a trained professional especially one who deals with the skin. He has been in practice for 37 years. Pretty good guy who has to be doing something right if hes been in practice this long.
Relax.... Stay off the internet. Consider talking to a family member. Getting the stress off your neck will help. Believe me I didn't want to tell my family what happened in any detail because I didn't want them to think less of me. I couldn't hold it in I burst. They haven't once thought less of me. Called it a bonehead move and dumb but none the less they make sure that daily I am okay and that when I start to freak out calm me down and remind me that the chances of this being the case are low and what everyone including Grace and Dr. Hook have told me. If I could argue with my Dermatologist I sure as heck wouldn't dare do it with Grace or Dr. Hook. Grace has first hand knowledge (along with being in the medical field) and Dr. Hook (along with Dr. HHH and Terri) have been dealing with STD's for a LONG time now. In fact Dr. HHH Dr. Hook and Terri )were all at the big STD conference and had some role in either presenting or answering questions. I don't think you can get much better then than that.
I am sure grace will tell you just about the same thing I did (I pretty much try and base my response to what she would say).
