Hedgehog

I have a 9 month old hedgehog and just 2 days ago he started bleeding from his toungue and it was really swollen i took him to one of my dads friend whos a vet but he really didint know much about hedgehogs he said he probably injured himself while he licked himself and so he said he would ask his manager about it and will purscribe a medicine. 2 days have passed and the swelling went down but he only seems to be drinking water he hasnt eaten or pooped but hes been acting normal. I read that if its to cold they wont eat but i have him in a warm room now so its not cold anymore. I also noticed he might have lost some teeth he still has the two front ones but from the side he doesnt seem to have plz help
