Hello, thanks for using health care magic Any symptom occurring in the genital region warrants an STD screening in individuals who have had unprotected intercourse within the past few months. This is so because, std can take some time before producing symptoms. However, there are a handful of other possible non std causes such as a bartholin abscess or bartholin cysts etc. Health is pre-requisite to day to day life and so in as much as you should not worry yourself, you should see a doctor for detail examination and tests and for appropriate diagnosis Best regards Dr Achuo
