Hi and thank you so much for this query. I am so sorry to hear about what you have been experiencing and the difficulties identifying the cause. From your symptoms, something is for real wrong. Though we have not found the cause, it cannot be said that you are not having an infection. I will like to make you understand that most tests look for the common causes and there are still so many other causes of genital infections that are not classically tested for like mycoplasma, ureaplasma etc. I think this is an indication to dig further down and consider the atypical germs. if a culture was not done, then you should also benefit from one. For now, I will like to suggest that you consider having protected sex until this infection is appropriately diagnosed and treated. If your partner has any symptoms, you may also want to get him tested so that it ay throw more light on what the possible cause could be in your case, too. Hope you find this helpful and provide enough information for you to act on. Feel free to return with more questions if need be. I wish you good health. Dr. Ditah, MD.
