Hi,
Welcome to ehealthforum,
Await your test results to confirm if the symptoms were suggestive of Herpes. It is difficult to comment on the labial bump that you describe without examining you. Avoid further self manipulation. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle. If infective cause is detected, and if you are sexually active, get your partner also treated simultaneously to prevent chances of re-infection. Avoid vaginal douching, use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes.
Take care.
