Unexplained Swelling on Leg

[capedthespian]

Help please!

My tortoises are currently being cared for by my brother while I am out of state. He just sent a photo of an enormous swelling on one of my Russian's legs, and has no idea what caused it. The tort is housed on eco earth, and there aren't any sharp edges in his enclosure. The swelling itself is pretty hard to the touch. Does anyone know what is wrong, and what can be done to bring down the swelling?

i'd get a vet to stick a needle in it and take a look at what they get out of it , maybe culture it , assuming it's not a tumor ........... might need opened up to drain and antibiotics ........ I've seen similar , just never on a tortoise , i'm guessing the treatment would be the same
