Zeltiq (coolsculpting) unlikely to work for buffalo hump
Unfortunately, Zeltiq is unlikely to work for the buffalo hump. Remember that zeltiq works best in an area of pinchable fat. Buffalo humps tend to be quite firm so the fat is unlikely to go into the probe.
By the way, buffalo humps can be caused by several things: 1) obesity 2) certain medications, 3) steroids, 4) cushing's disease. If you've not already been evaluated by a primary care doctor, it would probably be worthwhile to do so.
