Have Red Bump On Corona. Could This Be HSV-2?
Lack of pain, itching and clear fluid make diagnosis of genital herpes very unlikely.
A physical examination by a dermatolgist preferrably, shall orient the type of test to be asked, or at times, if its a chronic none specific skin irritation, simple local treatments even without blood tests could be sufficient.
I humbly think you book an appointment with your dermatologist.
Thanks and hope this helps. Would be glad to answer any further questions if need be.
Best regards,
