I've noticed a lump on Trevor's back in the past week or so It's tiny (about the size of my little fingernail, maybe smaller), hard like bone, and on the back left hip bone. Like, there's a similar bony place on the right side, but you can only feel it not see it, and I think that's his hip bone. It's like the left on is swollen or something? Anyway, it hasn't changed since I noticed it, and it may have been there longer, but I just don't know.
It kind of has me worried, because she's been acting pretty stressed this past week and not eating well. One night she kept jumping and nose-rubbing the side of her tank for almost half an hour at like four in the morning after I tried to feed her (the tank is in my room. I covered the cage with a scarf and went to bed, but I could still hear her). She's only been eating one or two roaches every day or two. She may just be slowing down after making up for her almost two-month hunger strike while I was at school, but noticing the lump has made me paranoid.
She doesn't seem to have any problems moving around, still looks fat, and doesn't seem to have any trouble when she does take roaches.
The only thing I can think of that is any different about her enclosure is that it's probably a bit too wet right now because she's been sloshing her water out into the substrate... Still burrowing though, so I'm guessing it's not too swampy.

Is this lump something I should be worried about? Could it be related to the slowed-down eating and acting stressed? I remember a couple similar threads about lumps on frogs' backs but I can't find them...
