remedies for ingrown hairs deep under the skin?

Hi,
Welcome to ehealthforum,
It is difficult to comment on the exact cause for the symptoms that you describe in vulval/vaginal area without examining you, and possibilities include Bartholin’s gland duct obstruction (due to infection/inflammation), inflames or infected paraurethral glands, folliculitis, ingrown hair, etc. The exact cause can only be made out after careful evaluation. Consider visiting your doctor/gynecologist at the earliest for thorough examination and further evaluation to look for the underlying cause. Treatment as appropriate (based on examination findings and investigations results) would be started to help you. Avoid vaginal douching, use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. Avoid sweat accumulation in the area. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
Take care.
