[|Human|] I am a 37 yr old female. For about a year I ve had a cyst or something on the lower right side of my back just above my hip bones. It started small about the size of a nickel and did not bother me. For the last month I have been experiencing terrible low back pain, and my right buttocks aches. The cyst or whatever it is, feels a little bigger than a golf ball now. It doesn t really move I don t think... If it does, it is very slight. Any ideas what it may be?
[|AI|]  Hello and welcome to Chat Doctor, Lump on the lower back above the hip bones can be due to a number of causes. A X-ray of the lower back is required to assess the probable site of origin of the lump. Since, the lump is just above the hip bone, it could be arising from the bone. If the lump is arising from bone, it is probably a cyst or bone tumor. If not arising from bone, the lump is probably a soft tissue swelling. Aspiration cytology can be performed on a soft tissue swelling. In aspiration cytology, cells are aspirated from the swelling, spread on a slide and stained with appropriate stain. The origin and nature of the lesion is determined with this investigation. Consult your primary healthcare provider for clinical assessment and first line investigations. Thanks and take care Chat Doctor.
