<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a red lump on my labia, its like in the middle of my lip. it is very smooth and soft but hard on the outer part. The skin around it is a bit itchy and painful when walking. im not sexually active. so it can t be an std but I do have a low immune system and get cold sores but I haven t had one for a good year or so now thanks  <response>: Hi, If I were your treating Doctor for this case of an itchy labial lump, I would come up with only one and one possibility that is a sebaceous cyst with super added fungal infection! Nothing to worry about this and try not to get infected there repeatedly! I suggest you to go for an FNAC test of the lump for confirmation if necessary otherwise take cold compress, local antibioticantifungal creams and also oral antibiotics and revert to us to relieve your concerns! Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
