And by raising your light up like that(they should be directly on screen) you are depriving your chameleon even more of the uvb he should be getting. He basically has gotten no uvb and so little calcium you have caused him to develop MBD. Pkease take him to a vet asap.

Please research the enclosure threads to give you some ideas. Please change out uvb bulb to linear tube. You need atleast one branch run horizontally below your basking light about 6 inches down so he can warm up. If it is warm where you live by all means take him outside for some natural...
He looks great too me and I told you how edema will come and go. Personally I think a vet is a waste of time and money, not to mention stressfull on the animal itself when it comes to this condition. Just my 2 cents.
