[|Human|] Hello , i have a smalll ball like thing floating in my lower back . It barely causes any pain until it is moved. Although sometimes when i lie down they are painful . Is that  something serious. How can i get it checked?I have read people posting similar problems, they have mostly been told about lipomas. Is this a lipoma? If so , the only way to get rid of it is a surgery , i already have a surgery scheduled next month , if you can please tell me any other way to get rid of it , probably by antibiotics , if any?Thanks Ishaan
[|AI|]  Hello and welcome to Chat Doctor, A mobile (floating) mass on the back can be due to proliferation of adipose tissue, connective tissue, other soft tissue, etc. A proliferation of adipose tissue is called lipoma. A soft and mobile mass on the back can be a lipoma, but few investigations need to be done before planning the treatment. A fine needle aspiration of the mass needs to be done. This test is an office procedure which samples the cells in the mass. These cells are examined microscopically and the nature and origin of the lesion is determined. On the basis of result of this test, further management will be planned. In case this mass turns out to be a lipoma, surgical treatment is the only modality of treatment. It cannot be treated by antibiotics or by any conservatively. Thanks and take care Chat Doctor.
