[|Human|] I have a deep lump on both sides of my upper buttocks,lowest part of spine area, basically top of my butt crack. Extremely painful, and lump has not reach skin and has grown in a few days from pea size to golf ball size. No redness, oozing, just painful and cannot see it visually. I have not had any accident or done anything to bring this on.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have some abscess or cyst or soft tissue tumor like lipoma or neurofibroma.  You should go for examination. If needed go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. 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.
