Okay, I'll get pictures immediately.

It is not in the same area as the scale rot; it is much lower. The wounds have healed, so I do not think I am pulling off any scabs. I don't think it's the scale rot coming back-- I monitor the humidity in her tank very carefully (kept at 40%-60%) and disinfect the tank either every two weeks or whenever I see feces with a 5% bleach solution. I am using paper towels as substrate, replaced every single time I clean. I treated the scale rot with a topical antibiotic but I do not know the name of the antibiotic.
