I have given you advice based on many years of keeping turtles without illness. Ultimately it is your decision on her care. I am not slamming your vet, I am sure she means well. The problem is that she probably does not treat many turtles. Again, I would advise that you get on some care sites and I think you will find that almost every site recommends a basking area and a heat source. I do believe if your turtles eyes were swollen while eating Reptomin in moderation than there is something else going on.

Good luck with her
