Blood Blister on my Juvenile Axolotl’s back 😖

[Lyned]

Hello! I’m new to this forum and a relatively new Axie Mommy (since last August). A week ago today I noticed Sunny, my juvenile lotl, developed a blood blister on her back. It doesn’t seem to slow her down, her appetite is great...I think it bothers me more that her.
Anyway...it’s gotten slightly larger but seems to have stabilized in size.
I placed a Catappa leaf in with her on Friday to help her heal but I haven’t noticed much of a difference. Water parameters are perfect and her water stays at a constant temperature of 63-64F. I’ll attach some photos. If anyone can give me advice...I’d love to help her get rid of this thing...poor baby! Thank you in advance for taking the time to help us. PS. The first pics are from today...the latter pics are from a week ago.

Woah, I have never seen that. I have no idea what could have caused it. Man, yeah, I really hope someone more experienced can weigh in on this. Sorry I can't help but how long has she had it? Could she have crawled under something and irritated her skin? Mine cut her tail once by waddling her fat butt through some drift wood.
