Thanks for your query.
If you have itching in labia it could be due to infection.
To treat infection you can simply apply a triple ointment containing antifungal,antibacterial and steroid
This will help treat the infection and reduce itching.
If you do not get relief please consult a doctor in person and get treated.
The wrinkle and bumpy feeling may be due to dehydration
as a result of applying vinegar,alcohol etc.
Please stop home treatment and consult a doctor(better a Gynaecologist).
