paralyzed uromastyx

Question
Hi. I have a uromastyx that is almost 6 years old.  He has always been healthy until about a week ago. He appears to paralyzed! He is not using his back legs at all and also it looks like he can't move his tail.  He drags himself around with his front legs, but latel doesn't even have much energy to do that! He is also not using the bathroom and not eating.  I continue to place him in warm water each night, just like we always have. I still take him outside each day for 20 minutes to an hour to soak up the UV rays. He has a brand new UV bulb and also the heat light for basking. He is housed in a custom built cage that is 85 degrees on one end and 130 on the other.  The humidity has increased lately to around 25 % and I can't figure out why. It is usually around 8% to 10%.  He has always eaten kale, bok choy, spring mix, apples sometimes, an occasional meal worm, he gets calcium sprinkled on his food as recommended on the bottle.  I have never treated him for parasites, but bought something last night to sprinkle on his food, but he won't eat!  Did I mention that he loves broccoli too?  (I hope thats not bad for him.)  I have always turned his lights off at night.  I have never taken him to the vet because the only reptile vet is over 100 miles away. I have been doing physical therapy on his back legs each day just to keep them going.  He appears to twitch when you rub his sides down near his hind legs/tail area.  Please help! Do you think it's metabolic bone disease?  Or constipation?  Or something entirel different? Any advice you can give will be greatly appreciated.  I look forward to hearing from you soon!

Answer
Hello Jennifer,

Have you used UVB light his entire life?  What type & brand of UVB are you using, a flouescent tube bulb or a compact/coil light?  
How often have you given calcium to him?  As an adult, he does need calcium 3 times per week still.  
Well, Kale & broccoli both can bind calcium absorption because of the high oxalate levels.  
The temperatures sound fine.  What type of thermometer are you using to measure the temps with?
I would continue to do physical therapy on his in the water that can help his strength.  
Do you think there is a possibility that he could have injured himself perhaps?  Just a thought.
It does somewhat sound like metabolic bone disease.  Some nutritional deficiencies can mimic metabolic bone disease.  
Do you use vitamins once weekly?  
Do you feed beans & lentils at all?  Do not feed kidney beans though.  He may not be getting enough protein though.  That could cause nutrition problems which would affect his ability to absorb certain nutrients & can throw off the calcium to phosphorus ratios.
