I have an adult male pacman who was fed calcium as a baby but then once he stoped growing he hasn't been fedcalcium for about 6 months. Not my decision..I just took him from the original owner cuz they couldn't care for him anymore. His back leg is noticeably swollen around hip/thigh/knee area and its almost feels as if the hip and knee are dislocated but they aren't. The swollen area around the hip is hard like the hip bone by socket is bigger or bulging out. By his knee he has a red bump/abcess looking wound and that is also hard under the skin like by the hip. His leg moves fine and he still uses it so obviously his hip and knee aren't dislocated. He doesn't favor it and it doesn't seem to bother him but something is def wrong. He hasn't been dropped or smashed. Eats worms...has bead a beast..in a 10 gallon tank..has heat pad on bottom..temps are in the 75-78 range and humidity is in the 80% range..goes up to 85 when adding. More moisture to beda beast. His substrate is always damp..not swampy but clumpy. He has a water dish and a clay pot to hid under along with a big fake broad leaf plant to hide the pot. He is by himself and is now getting calcium starting today when I got him. He ate 4 night crawlers with calcium. I soaked him in calcium water as well..not sure if he would absorb that but figured it couldn't hurt. He has a light but its strictly for light and not heat. His substrate he can bury in but chooses to sit under the pot in a little divit he made in substrate where its warmest. He doesn't have red on his legs or body. And other than swollen leg and the one bump he seems perfectly fine. He was given and still is given spring water.
