Now if you are talking about the discoloration on the side, that i can not tell. If anything starts to turn black, then you need silver cream which is only by prescription. Never touch with bare hands and know burns can take years to resolve with chameleons. it they lose their spikes it will be raw underneath at which point infection is your enemy. alsoburns are very painful and will cause a cham to stop eating, drinking etc.. You should do an entire husbandry review here.
