Hi,
Welcome to ehealthforum,
It is difficult to comment on the cause for the vulval bumps that you describe without examining you. It is likely to be due to inflammation caused by shaving or chemical irritation etc. Consider visiting your doctor/gynecologist for examination and further evaluation to look for the underlying cause. Avoid any self manipulation. Get started on treatment as indicated (based on examination findings and investigation results). If infective cause is detected, 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 tight fitting clothes. Make sure that your undergarments are washed well and have no traces of detergent in them. Drink plenty of water. Maintain healthy diet. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any unusual/new/abnormal symptoms immediately.
Take care.
