<s>[INST] I have a tiny grain like bump inside my labia minora, it s actually right on my clitoral hood and I can see through it if I put a light on it. It does not hurt when I touch or at all. I have not had any type of sexual contact with my partner or anyone for a while now so I m pretty confident ruling it out as an STD. About 2 months ago I got tested for STD S at my gyno they never called back so I m assuming everything came back normal. What could this be? [/INST] Hi,This is likely to be a Bartholin's cyst. This is a common cyst that can develop in this area. It is not a serious problem and can be left alone if it does not cause any pain. If it becomes painful or enlarged then see your doctor as you may need antibiotics. Regards,Dr K A Pottinger </s>
