hello all! i havent posted but once or twice, but need some help and thought you guys were my best bet. let me tell you a story...

back in the middle of september, i bought a 1 month old orange granite female bp. the night we brought her home, she took down 2 live hoppers without an issue. from that night forward, once a week she took down 1-3 live hoppers, depending on their size, for quite a few weeks. then one week, i tried her on a smaller adult sized mouse. although she took it down, she took awhile to get it down. since that night (about 6 weeks ago), she has not shown any interest in food. a month ago she was down to 69 grams, and is now down to 57 grams. she has been to the vet, who did a tube feeding and said to keep trying on small prey (pinkies, etc), but she has shown no interest at all in food, and is starting to waste away. she will be returning to the vet very soon for possible blood tests (fecals are impossible because there is nothing in her to get anything out of according to the vet), but im hoping for some ideas.

ok, the basics on her care
small tub setup, temps 90-92 with the basic gradient using human heat pad, 2 small tight hides (one on each side).

feeding attempts have been both f/t and live mice and rats (hoppers or fuzzies), and one live pinkie (left in over night per the vet). we have tried feeding both in the tub and in a different enclosure. no luck with anything, she just either sniffs and runs or balls up completely and hides her head as far as she can.

the biggest oddball situation is the lump that formed, went away, and now is back. of course it went away RIGHT before going to the vet, so he did not see it, but it has come back. there is NOTHING in her system according to the vet, so im thinking an infection or something? it is right above her vent, and is about 1/2" long.

here are a bunch of pics. yes, i know how skinny she is, but she was much bigger 6 weeks ago when she was eating. you can see the bump in several pics. if anyone has ANY ideas, please let me know. obviously she is going back to the vet, but im hoping for some ideas we can give to him, because he seems a little stumped too, and he is one of the best in the state. thanks for the help up front! here are the pics that were taken tonight.
