Not sure what's wrong..

[Qwerty3159]

Yesterday my snake shed, complete. He also shed around the 29th of December and then the 3rd of the last month as well.
I noticed today he was moving very slow and seemed to be having trouble getting around. I picked him up and his whole underside felt very soft- softer than normal. Are snakes softer after they shed? I don't handle this guy a whole lot because he's so little and I don't want to smoosh him so I wouldn't really know lol. Anyways the lines between his ventral scales have darkened a bit looking like stripes but I don't think that is the problem. The problem is he's just acting bizarre, moving strangely, and holding his back end off the floor.

Overall he's been lethargic and slow-moving, has been holding his tail off the floor with random parts of his body elevated, and hasn't been doing much. He also crawled right through his food without glancing at it, which is very unusual with him. He's doing some tongue flickering now and then so he's not totally listless He's been pretty much problem free and I'm stumped.

Any advice?
