renee - I am sure Carlton would agree that giving you other suggestions may or may not be helpful. This is some sort of abnormal growth that really needs to be properly diagnosed - it cannot be done on a fourm, even by a vet. I made some other suggestions to you in your additional post above.
Whether it is supplementation or some organ dysfunctiuon chameleons do not heal quickly nor do they show symptoms quickly. Point being that something has been going on for a while in order for these to be so large now and will need proper treatment.
I know you say you do not have a vet - where do you live? Did you look at the link I gave you above for vet resources? In a previous post you said you are well read in their care, well that should include having an accecssible herp vet. I am not reprimanding you I guess I am always surprised when people take on an animal (any) without having a vet lined up before purchasing.
Hope all goes well with him, not sure what else to tell you.
