Hello,
From your symptoms, it can be vaginal cyst, molluscum or genital warts(caused by HPV infection).
Apply warm compresses,Neosporin ointment and calamine lotion and avoid messing with it.You can take anti-inflammatory pain killers like ibuprofen or acetaminophen. If the lump persists then it will be best to get it evaluated from a dermatologist.
Diagnosis of genital warts is usually clinical, made by visual inspection. Genital warts can be confirmed by biopsy but Sometimes we can use an enhancing technique called acetowhitening. This technique involves the application of 5% acetic acid solution to the area of suspicion for about 5-10 minutes. Infected areas will turn white. You can get it done.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
I just wondered if this is normal anyone else have it?
