I just noticed a hard bump on my Veiled Chameleons left leg, it is in the inner thigh area just above the knee. I don’t believe it was there before. He is mostly shed, but still in a shedding cycle. I am not sure if that has anyone to do with it. I do have UVB lights. I have had him almost a year. He is approx 11in long. I look at, and talk to him daily (I know they are deaf, but like to talk to him) I did not notice it yesterday. I took him out, and touched the area, it is very hard, but seems not to hurt him, and he is still eating and acting normal.

Could be an abscess (herp abscesses are not soft and pliable like mammals), or if it is along the leg bone possibly a healed fracture? What calcium/gutload/lighting do you use? If it does not go away or gets larger I'd have a vet check it. It has nothing to do with shedding.

I use flukers gut load, and a 36" desert 7% UVA/UVB bulb

How often do you change your bulb, how often do you dust and with what? Bulbs don't emit UV forever. The bulb will operate long after the UV production drops way off.

If your cham doesn't have other signs of MBD (crooked legs, bumps along ribs, weak grip, shaky trembling movements, collapsed casque, lethargy) it is more likely some type of abscess or localized cyst.

you said your UV source is almost a year old. That means it's been pretty much ineffective for about 6 months. Flourescent bulbs that emit UV should be replaced twice a year every six months. You need to get a new one, definately.
