Question: Hurt gill?

[sebguy]

So my axolotl-ari has been eating fine moving about normally and her behavior hasn't
changed but after the last tank clean i noticed that she was keeping one set of her gills
pressed up against her body upon further inspection i realized that there was a small bump on her head where the stalk connects to the head. Any ideas if she could have hurt herself?
and if so what should i do?

Well, it could be a lot of things... Pictures would help.

Does it seem to be hurting her, or does she pretty much ignore it other than the gills keeping close?
