A few days ago I noticed one of my chinchilla's toes was red and swollen, it almost looked like there was an abscess or a growth. There was no foot injury that I am aware of. He still puts weight on the foot when running/walking, but other times he favors it, pulling it in close to his body. I watched the toe for a few days and it continued to swell. I took him to the vet and the vet thought it was a blood blister caused by a splinter. He popped the blister (lots of blood came out) and cauterized the wound with silver nitrate to prevent infection. This was 2 days ago, and I am noticing the toe beginning to get red and swollen again. I plan on taking my chin back to the vet as soon as I can get an appointment, but I am worried that this is going to turn into a repetitive cycle. Does anyone know what this could be? I have done some research, and I don't think it's bumblefoot. It doesn't seem to resemble any of the foot issues I have learned about. I can't afford to keep running my chin back to the vet. Any thoughts?
