It is the other way around:
IgG is the long term antibody and permanent for life (mostly) whereas IgM is short term (but can appear at times throughout your life as well). This the best interpretations are as follows:
positive swab but negative IgG, IgM result irrelevant may be positive or negative... recent infection
negative IgG, IgM result irrelevant may be positive or negative followed weeks later by a positive IgG... recent infection
positive IgG, IgM irrelevant maybe positive or negative... most likely a longer term infection
If there were multiple sores on 9 July and this is unlike anything you have had before, then there is little doubt that you were infected most likely on 2 July or a couple of days before that. March is simply too long prior to 9 July for that to be a realistic possibility.
Now think back, was there oral sex involved on 2 July or the few days prior? If so, you will need to check that your swab was properly typed. Most cultures are not typed and just assumed to be HSV-2. Oral sex can result in the transmission of a partner's oral HSV-1 (cold sore) infection to your genitals. Does your partner have oral cold sores?
It is a shame the culprit has not been identified, your doctor was pretty thorough in testing for micoplasma of which there are numerous that can cause these symptoms. The ongoing treatment of antibiotics is also therefore leaning toward this not being bacterial.
Now the complicated part, is HSV-1 at play here? Now the complication is that the odds of having HSV-1 orally already from childhood exceed (by a factor of hundreds) the chances of experiencing just an outbreak of herpes inside your urethra from oral sex (as opposed to on your shaft for example). Hence the conclusion you need to reach just at this time is that you have had an oral HSV-1 for most of your life and do not recall any cold sores. If either of your parents have oral cold sores, your odds of having it given this information are nearing 100%.
The added implication of this conclusion is that you, especially as a male, are immune from a genital HSV-1 infection!
Thus the odds really remain strongly with another cause. It may be time to look more closely at kidney, bladder or prostate issues.
I understand it's just crazy...I came clean and neither of them want me anymore like I am damaged goods. They both act like it's all my fault. And everything I read about it it either says that you have an outbreak 2 to 20 days after exposure or that it lays dormant and then you have an outbreak...
I read the stress. And all this other stuff can cause you to have an outbreak. But I had a baby in July 2015 and my son's father was my only sexual contact for about 1.5 years. If one of them didn't give it to me then I don't understand why the stress of being pregnant being a single mom and having so many other life crisis not cause an outbreak until now....
I have really bad anxiety and I was taking medication for it and stress and all these issues that worried me why did not have an outbreak until now....just upset
I dont know who gave it to me. My suspect says hes clean. At the end of the day you cant change whats happened. If the ex gets no symptoms he may believe hes clean. You need to just focus on trying to accept it now. Its hard at first but in time it gets easier for most.
