Honestly, it really doesn't look like it to me. It might be the very beginning/early stages of scale rot, but it's not anything that would cause an internal infection at this stage. If you have a vet who does herps in your area you could always take it by and see if they will prescribe you a topical. Betadine soaks are a common suggestion, but I'm hesitant to suggest it for something so minor like this. Maybe a diluted Betadine application to just this area would be OK, and see how that works. What kind of substrate are you using, and what are your humidity levels?
