<s>[INST] I have a pea size bump or knot on the left side of vaginal lips not the one that grows hair but they other set not sure whats the name of them but its red and it hurts. I am not sexually active so i dont know where it could have come from. Can you please help? [/INST] Hi, dear. I have gone through your question. I can understand your concern.  You may have some cyst in that area.  Benign cystic lesion is common in that area.  You should go for examination.  If needed go for excision biopsy and histopathological examination. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
