Bubbly mouth

[Jrich]

Alright it's been a bit now. She went through a round of shots (every 3 days for about 2 weeks). The vet and I noticed she had some hard lumps on the business end of things and he thought she may be constipated, the last time she ate was in May but I do realize snakes can hold onto meals for awhile. Over the weekend I have been giving her warm soaks in the tub and massaging the little lumps as suggested by the vet to get her to finally poop.
As for the bubbling, I just finished soaking her and she kept yawning and she snotted from her nostrils some. Sigh. The shots are not expensive but it seems like nothing is working and she's down to 200grams. I offer a hot fuzzy every few days at night but she ignores it. She still appears to be active during the wee hours because I will wake up to her knocking stuff over in her tank as she slithers around. I really don't know what to do.
