My Packman I recently acquired are a night crawler night before last now he won't eat and seem to have a very hard lump in his side and it feels like it is just under the skin on his side could he have ate something before I brought him home and now it is bothering him ,is there anyway to help him expel it if the is somethig in there and he was had his mouth partially open. Also what are the best food choies t offer Any advise would be appreciated.
