Turtles can get pseudogout, gout, and calcification of soft tissue. This can be due to issue with husbandry. Have your turtle examined by a veterinarian, they will examine the lump, and can review your turtle's home care. Turtles can also get abscesses that they are often able to wall off from the rest of the body.
It is really very difficult to treat this lump at home by yourself because this bump can be an abscess or infection or it can also be injury. Take him to herp vet for proper diagnosis and treatment.
LOL, I hear you have to 'Swab the sore area with some Betidine solution, and let it dry for a bit, then smear on some antibiotic ointment and let that dry for an hour or so.' but I haven't tried it on mine (who has TWO lumps on his neck!) because I'm away from home.For me, every day it got worse and the second one developed just 3 days ago. We took it to a vet friend of my mom's and she said it might be a tumor.I doubt it though, because I see that a LOT of people are having the same problem! So take him/her to the vet and if what he/she says didn't help, and nothing on the internet did, then he might have to put him out of his misery. I'm sorry! I might have to put mine down so...ok, hoped it helped!!!
Dear, try to wash him with warm salted water as it helps to remove black stuff from your turtles shell or might your dog is suffering from abscess of the tympanic membrane i.e. Ear infection so its better to consult a doctor for its removal. Animals can't speak so it's our responsibility to take care good care of them.
