at 3 years of age he really is a very very old hammy and it sounds as if he is ready to make his way to the bridge soon. If you think he may be in pain then seeing a vet is the best thing to do however often they just are winding down when they behave this way and you may decide to just let him make his own way peacefully in his nest. I'd cover him with a blanket over the cage at one side so he is quiet and dark. Leave some food near his nest and a small bowl of water and maybe a little cucumber chopped up. maybe check every few hours. Dont be surprised if he lies out in the open as this is not uncommon in hammies why are passing. I hope his path is gentle.
