[|Human|] Hello. I found a lump on the left side of my lower back about 2.5 months ago. It is the size of a dime and is not visible and can only be felt when pressure is applied to the skin. It hasnt grown or changed and is painless to the touch. However, I do have back and leg pain. I am a 22 yr old female. I dont smoke or drink and am relatively healthy. No history of cancer in my family.
[|AI|]  Respected user, hi I evaluated your query thoroughly.* According to the narration, it is most likely to be Lipoma (accumulation of subcutaneous fat) which can give rise to local discomfort but not leg pain which seems to be separate entity than this. Hope this clears your query. Welcome for any further assistance. Thanks for using Chat Doctor .com & giving me an opportunity to assistWishing you happy healthy life ahead. Regards dear take care.
