Hello, what color are the bumps?
Any pain when passing urine?
How long has it been a problem?
Thanks for the extra information. So there is no discharge at all?
What is the appearance of the bumps (size/color/texture)?
What happens during a period?
With vaginal redness, itching and bumps then we need to exclude allergy such as to soap, toiletries, spermicides and even sanitary products. Antihistamine tablets can be useful in breaking the itch-scratch cycle.
However bumps that are pale/white need to be examined to rule out warts or other lesions. It does not sound like herpes which tends to crust over however your doctor may suggest some swabs to confirm the exact diagnosis.
