So, if you are only giving this supplement, immediately stop giving this to your chameleon. You need to be giving Calcium "without" vitamin D at every feeding, and Calcuim "with" Vit D only twice a month really. The spots you are seeing might be calcium deposits in the soft tissue after...
You should also try and listen for crackles in breath when gaping, like someone above mentioned. Make sure its not an resp infection. I say that because you mention the chameleon is lethargic as well as gaping.

You did the right thing by admitted you had questions...this place has answers. Listen to people here, and follow advice from this and other threads and you should be good. Coming here for help shows you care, and is probably the most important aspect of owning a chameleon....besides...
You wanna keep a very close eye on that. If it gets bigger, please make a vet appointment. If it does not grow in size, but does not heal...probably also make a vet appointment. If it begins to shrink or heal, it's most likely some injury like stated above but less to worry about. Just my...
Go to Lowes or Home Depot and get a window winterizing kit. They are clear sheets of plastic you can put on your windows in the winter to keep heat in and cold out. You can use it the same way on most of your enclosure. Just remember to leave one side or part not covered so you have some...
