Thanks for your query
As described by you black dot which is itchy and tender with clear fluid. They may sometimes are associated with Painful urination and an increase in vaginal discharge
.Do you experience fever , muscle aches.
As per Your description It appears to be Genital Herpes
You can take pain killers like paracetamol
and anti-itching medicine like Cetrizine.
can help in reducing pain and healing genital sores
If you experience reoccurring bouts of herpes, it is important that you take the antiviral medication
before the actual sores manifest. They should be taken when the tingling, burning, or itchy sensation occurs. Warm baths can also relieve the pain caused by the bumps/blisters.
I hope this will help you
