Gyn diagnosed a "sebaceous cyst" on my inner labia majora. she said it's something i have to live with and removal is not an option because removal could cause infection. please tell me if this is correct. it's nearly impossible to get 2nd opinion?

Something does not add up. We do surgery on vagina all the time and take care of the infection. Why is second opinion not possible? You do need to see a different doctor. Try the local clinic of planned parenthood, if you cannot afford a second gyn. Wish you good health!

find a gen. surgeon or a Urologist or another Gyn. Infection post removal is rare. You should be fine.
