Hi all and thank you in advance, I've recently come to care for an adorable male leopard gecko that previously belonged to a family acquaintance. While I wasn't told the specifics, I'm assuming they felt they could not provide adequate care for him and judging by the state he came to us in im inclined to agree due to the following reasons. Despite his small size and possible malnourishment (which we are on good tracks to fixing) the thing that concerns me most is a rather large bump near his hind quarters, it is red and he becomes quite agitated even when something like a cotton bud is very lightly pressed against it. Any help would be appreciated and thank you in advance
