Just an update to all:Yeah, the blood results showed him having poor calcium levels (1:1 ratio with phosphorus). Strange that all these neuro symptoms didn't really start until I began treating the hypocalcemia (in the last week). Maybe just a coincidence...
The vet said based on what I have been giving him an overdose/hypercalcemia is unlikely.
Drax seems to be improving. He is certainly better today than he was this time last week. Along with his walking/posture going back to normal, the tremors have become less frequent... I actually didn't see him do it at all yesterday, though his body does vibrate a bit when I hold him (maybe some of that is nervousness from me continuing to syringe feed him). He is very active and alert and yesterday he was a beautiful bright yellow (he is a super citrus dragon, but lately he has had a more dull color).
Despite these improvements, he is still not showing any interest in food. I want to try to pull back on force feeding him as he isn't in as bad of shape, but I don't want him to regress and lose any more weight. This is especially the case because he is still at his lowest weight since all of this started (230-240 grams).
Also, as a side note, when he does go to the bathroom, his urates are very small... almost like a drop (they are white though).
