Im assuming that your BF is kanarybird. IF so it seems hes come to the conclusion its a impaction,

With that, a impaction can build up, wether of too large prey items, or a loose substrate (like sand), expecially in a baby, and it can collect and become a ball, or lump. This can cause a irritation in the digestive track, and as the digestive track is right near the spine, the impaction can irritate the spine and cause parylasis in the parts following the impaction, or partial paralysis. To treat this, i have given a few suggestions in a Pm to him, but a vets your best option.

UVB dificiency is also associated with the same problem, with this if its early it can be fixed with the right UVB light, In any case she needs the right UVB or this will happen even if it has not already. What happens is beardies use the UVB to synthesise vitamin D3 in there body and this, along with calcium keeps there bones hard and body running. IF the dragon does not get this UVB, or the correct suplements, his bones may be soft, and can break easy, but also usually his back leg or legs may slowly stop working as well, and soften and over time paralysis can grow. This is called Medabolic bone disease. Id get a Repti-sun 10.0 tube, (not compact), you can get the fixture at home depot, petco/petsmart (check fish hoods/recepticals section, these are cheaper then reptile versions but work just as good) or other stores like that for the correct length fixture. Then with the bulb, use this and it will help a ton. The repti-sun 5.0 is ok, and all others are probably too strong for the size tank you seem to have, so this is the best bet, strongest and best for the animal. A vet can also help treat this.

Only a vet is qualified to tell wether its impaction or MBD, and we cant over the internet, but to give baths can help with a possible impaction and has little ill effects, and a good UVB is a must in any situation, so to get this is needed regardless.

Hope this all helps, and i hope you can figure things out, Good luck,
Ben
