I was wondering if anyone can help me out. About two months ago I noticed a lump on my Jackson Chameleons (Ted) Foot. I have attached a picture. It does not appear to have gotten any large or affect his walking buy it does have me concerned. It is just a lump and appear to have a black dot. Other then that he appears healthy, eats and drinks well. Give in Calcium 2 times a week. Not sure if it is an infection of some sort or not. Any suggestions?
