small white bumps that itch, Dr said not herpes...

Hi,
Welcome to ehealthforum,
It is difficult to comment on the cause for the vaginal bumps that you describe without examining you. You should consider taking a second opinion from another doctor/gynecologist or your doctor/healthcare provider. Go ahead with getting a thorough examination (and further investigations based on examination findings) to confirm the underlying cause. Treatment as appropriate (based on examination findings and investigations results) would be started to help you. Consider being 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. Avoid vaginal douching, use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. If infective cause is detected, and if you are sexually active, get your partner also treated simultaneously to prevent chances of re-infection, and avoid having intercourse while being on treatment.
Take care.
