Illness/Sickness: My axolotl has small lumps over her

Hi i have just looked at my axolotl (Axi) , and she is covered in lumps. Sorry if I Don't describe this well but I don't know how. They are all over her chin, there are some on her head (some indent in some are lumps and the most noticeable in pictures the ones down her back around her back fin. She seems perfectly happy, still has a big appetite, is walking and swimming round fine, will still have a chomp on my finger if she gets the chance. But I am really concerned she is also covered in tiny white Un risen spots (I couldn't really get these in the photo) so what could this be? Is it just something I haven't noticed before? Or is it something I should be concerned about? I can't test my water as I don't have a water testing kit yet but if it needs testing I can take it down pets at home. Thank you in advance.

I don't see anything amiss. Just the normal skin texture an axolotl should have. If you think I am missing something, try to get more photos.

I'll have to try to get some more pictures tomorrow as she is not cooperating.
