Are you positive that this is Metabolic Bone Disease? MBD usually has more significant signs than a single swollen foot. I wont rule it out of course, however, based on the photo and your telling us its in the foot specifically, it looks more like Edema or Gout.
will if u dont mind would u be able to send me a few linkds regarding Edema and Gout.. becasue maybe we have been going the wrong route on curing this... ive treated it with calium drop and a changing my dusting dates!
Edema is a symptome of other things that are wrong, kidny isuues, under/over supplementing are the most common causes if you see edema you have to look into your care as someting is wrong.
If that is not an injury causing the swelling i would guess gout as well.
Fabos, unfortunately, my favourite link about Gout is on the Chameleon Journals website which has been down for a few months or so now. I did not save the information offline so I can't link it to you. However some other decent sources were cited.
I agree with Brandy, IF the swollen area is not cause by physical trama, then it just spells GOUT to me.
Gout. A disease caused by excessive uric acid (urate) build-up in blood and extracellular spaces. The symptoms of gout are most obvious when they occcur in limb joints.
There is one more possibility and more likely she has an infection of her foot. This is not MBD and it could be gout but would affect more likely her joints not foot.
