We obviously cannot say with certainty , but I think this is extremely unlikely to be herpes for numerous reasons . First , your boyfriend is unlikely to have genital herpes given his age , sexual pratices , and lack of ever having symptoms . Second , your boyfriend did not perform oral sex on you , so even if he has oral hsv 1 which more than half of people do there is no risk of him infecting you that way either . Third , genital herpes is less contagious than most people realize . Even if your boyfriend definitely had genital herpes , the chance that you would get infected from a single , or very limited number of , sexual encounters when he did not have visible symptoms is very low . Fourth , your symptoms themselves are very inconclusive . There are numerous possible things that could be causing the symptoms that you are experiencing . Plus , it is hard to know what you mean by the spot hurting . The degree that herpes lesions are uncomfortable depends , on a large extent , to where they are located . But they are usually at least painful when touched directly , and people often describe them as feeling raw . Fifth , you had also shaved recently and have a history of ingrown hairs . Shaving can make it easier for the skin to get infected with whatever , because it can cause tiny microscopic breaks in the skin . And it ' s also important to remember that when people have sex they also exchange bacteria and fungal cultures and these sorts of things can cause various reactions as well . The only other symptom I ' ve had is feeling nauseous in the morning , but sickness is going around my campus right now . Herpes does not cause nausea . I ' m really worried . Does this sound like it could be something ? No need to worry . There are numerous possible causes of your symptoms , most of which are completely nonSTD related . And the chance of this being herpes is very low . Low enough that I personally wouldn ' t worry about it . I ' m planning on getting tested soon , but given it ' s only been about two weeks , would a blood test come back accurate ? No , it would be too soon for a blood test , though if you are really worried then you could get your lesion swabbed . There are basically two ways to test for herpes a swab test or a blood test . A swab test requires that a suspicious lesion be present . If a lesion is present , it can be swabbed and tested immediately . The swab test must be performed before the lesion has started to scab over , so if you have a suspicious lesion it is important to not wait too long before getting it tested . The current type of swab test used for herpes testing should be a PCR swab PCR Polymerase Chain Reaction . It replaces the older type of swab , a viral culture . PCR is 4 times more sensitive than viral culture . IE Viral culture is FOUR TIMES more likely to report a false negative . Be sure to ask your provider what kind of swab test they are using , and get a PCR swab if possible . Alternatively , a blood test can be done . But a person must be infected with herpes for up to four months before it will register on a standard IgG blood test . A blood test works by detecting antibodies to the herpes virus , which the body starts creating after being infected . But it takes time before enough antibodies are generated to register on the blood test , and different people generate them at different rates . About 50 % of people who have herpes will have detectable levels of antibodies by 3 weeks post infection . 70 % will by 6 weeks . By 4 months , about 95 % of people will have detectable levels of antibodies . So a blood test may not reflect any change in a person ' s status ie negative to positive in the most recent period of up to four months . Furthermore , a blood test will not tell you the location of the infection , which can be problematic for people who have never experienced symptoms , or experienced very ambiguous symptoms that might have been caused by something else . For these reasons , the swab test is preferable . Ideally , if a suspicious lesion is present then both tests are performed . Note that the current standard for blood testing is the IgG test . An older blood test called an IgM test is still used by some clinicians who have outdated herpes knowledge . The IgM test is extremely unreliable for diagnosing herpes and should definitely not be used . Make sure you get an IgG test done . By four months postexposure , the IgG test correctly identifies hsv 2 about 95 % of the time . Unfortunately , the IgG is not nearly as sensitive at detecting hsv 1 . It misses a full 30 % ie more than 1 in 4 of hsv 1 cases . There is another test available in the U . S . that is much better at detecting hsv 1 and slightly better at detecting hsv 2 , called The Western Blot . But it must be specially ordered through the University of Washington . You can order a kit from the University , have your blood drawn locally , then send the kit back into the University for analysis . For further information on this option , see this page , and scroll down to the Where Can I Get Tested section , or this page , and scroll down to the HSV Western Blot section . Also , it might be a good idea to take some photos of your symptoms that you can hang onto for future reference , or show to a doctor in case things change before you are able to see a doctor . But sure to take good quality photos with adequate lighting , in sharp focus , from multiple angles , and some closer and some further away so the viewer can get a sense of scale and also be able to identify the general region of the body affected .
