Brought home a severely underweight BP baby. Please help me get her back on track

[Spoons]

So, just a lil update!

She is off her antibiotics. She is doing *wonderfully* - she's an active, curious little snake with an incredible appetite. She's been steadily gaining weight, she is eating hoppers. Still a little thin but a HUGE improvement. She crawls around at night, hangs out with her head peeking out her hidey huts to watch what's going on. A little hand shy (understandably) still. She has just hit the 100 gram mark - she was 52 grams when I brought her home.

However. She is still getting big fluid pockets under her skin. They do not seem to bother her unless I poke at them, which I try to not do. I brought her back to the vet two weeks post-antibiotics because the pockets were larger than I've seen them. They drew the fluid off and sent it for a fluid analysis, and said that she's looking really good, and that they have no idea what it could be. They looked at the fluid under a microscope and said there really wasn't anything to see - there was like one white blood cell, a bacteria cell that was likely cross contamination from the skin. Fluid analysis showed not much - a couple cells here and there, but no infection (that they could see), no inflammation, no bacteria. A bacterial culture of the fluid would be useless since there's no bacteria to culture.

In short, they're baffled. I did post in a group on Facebook, and it was brought up that there's a possibility of organ damage which can cause fluid buildup in humans, so possibly something similar in snakes. A few people said they had similar pockets on their emaciated rescue BP - a few said they spontaneously recovered, and one said their snake passed. The vet said we can do more testing, but I opted to just watch and see, and the vet agreed that because she is, for all intents and purposes, a healthy snake otherwise, that is a valid way to go and to just keep an eye on her and jump on it if she starts to look sick or go downhill. If the fluid pockets get too big, I have the ok to draw the fluid off of her - I have not done so since the very first time to check for blood, because I am hoping the body will reabsorb it on its own. I don't want her getting dehydrated, and the less needle pokes the better, imo.

So! That's where we are at with her. Here's a few pictures - the red arrow points to the start of one of the fluid pockets. the last pic is her post-vet just an overall pic of how she is looking! She's a little fighter and I am still pulling for her. If anybody has any insight on the fluid, I'd love to hear it.

Posting pics in the following post for ease of doing - For some reason on the computer the pics preview HUGE. I'll add them in a sec via Tapatalk.
