Hi, thanks for the question. It seems that you are having a mild chronic infection and that has led to this. Most likely a small gland must have got infected and pus collected in it. The hole is formed due to some damage to the surface cells that fail to get re united and heal leaving behind a hole. Later the tip of the hole may get sealed due to any debris and all the secretions get collected inside the formed space leading to lump formation. If you squeeze the lump, toothpaste like material comes out. This is similar to what happens with chronic acne [pimples] where a sort of cavity forms and pus gets collected in it and squeezing may leave behind a hole as a part of the healing process. However a few home remedies will most likely resolve this issue. You need to clean the area with mild soap and warm water. Try to squeeze out all the contents at one go. The hole will most likely remain. Apply antiseptic solution like betadine or savlon on the area two or three times. You may need to do this 3-4 times until no more collection comes out. Warm [not hot] compresses in the area help in faster healing. If you are not able to squeeze it, you will need to see your physician who will get it removed for you. This will take care of the issue most of the time. Hope you find this helpful. Thanks for the query and have a good day. Dr. Madhuri Bagde Consultant Obstetrician and Gynecologist.
