[|Human|] I have recently lost a lot of weight, going from 200lbs to 140lbs in about 4 months. Since losing this weight I have begun having the strangest issue with my tailbone. I feel as though there is something, a golf ball shaped something, at the base of my tailbone. It shifts and moves depending on how I am sitting, but it is always there. Its like constantly sitting on a huge hard lump! I cannot get my physician to take this seriously, it is driving me nuts! And no it does not hurt.
[|AI|]  Hi. Thanks for your query. Noted the appearance of a painless golf-ball like lump at the tailbone after losing weight from 200 lbs to 140 lbs. It does move and shift, but always there. I could not understand why you can not get your Physician to take this seriously. I would advise you the following in such a situation.- First go for MRI of the area, and you will have either a confirmed diagnosis or can have it ruled out. If it is present you have to consult a General Surgeon and get this first FNAC and then to get this operated to get rod of the problems and to get a confirmed diagnosis by histopathology examination.
