Help Any Info?????

Merged both thread for you :gj:

Possibly both. Make sure he has fresh water, and perhaps a soak. Give him time to destress, I don't know how long you've had him(but you said you don't know when he last ate). At least a week with no handling, to let him settle in before you attempt to feed.
If he's underweight, there's no fast way to get the weight back on, you'll just have to feed him on a good schedule.

My guess is either dehydration, or he needs to be fed.

I still don't get what exactly is going on, so can you post a picture or video?
