I think my Bearded dragon had MBD. He is shakey, dragging his back legs, not moving around a lot, has not pooped in a few weeks, not growing or shedding, barely eating. I changed his uvb bulb to a uvb tube and got vitamins and calcium powder to coat his food. He has been moving around a little more but still no pooping and still shakey and dragging. What else can I do? He also has a bump in his tail I am worried about.
