Hi and thanks for the query,
az good physical examination by your primary care
physician is usally sufficient to make a claer diagnosis. Infections could range from herpes
viral infections, yeast infection or bacterial. Appropriate diagnosis determines the treatment of choice. A physical examination shall orient your treating physician on the type of blood tests or other tests to prescribe. Avoiding un protected sex during this period is fundamental. Advising your sexual partner if any to also seek medical follow up could be useful. I suggest you consult your primary care physicia for a proper medical check up.
Thanks and best regards,
