Signs of metabolic bone disease include hard knobs in the long bones of the legs, bumps along the vertebral column of the back and tail, bilateral softening or hard swelling of the lower jaw, and softening of the plastron or carapace. All of these signs may be felt before they can be seen, making a careful physical exam important. Visible signs of moderate to severe MBD include jerky gait when walking, repeated tremors and twitches in the limbs and muscles of the legs and toes when at rest, and shakiness when being held. (The occasional single myoclonic jerk that happens is not considered indicative of MBD.)
my tortoise suffers from mbd due to the care of its previous owner, despite having a
moderate case of MBD she still has.....let me put it this way, it RUNS to the plate of greens the moment i put it in the tank.
she's doing well btw, a good diet with a multi and calcium suppliment and a strong uvb/uva bulb go a long way
