My chameleon burnt the tip of his tail about 3 weeks ago on his basking lamp when he was out of the cage. It didn't look bad, the skin was somewhat discolored but it didn't look serious. I figured it would heal up and color would come back after the next shed. But within the last 2 days it has gotten bad. I've put two pictures up, one from about 8 days ago and one from today. Should I take him to the vet? I don't want it going farther up his tail.
