Hi, Sorry no-one has replied sooner. Sorry to hear about your hedgehog – it must be very distressing for it and you.
I’m guessing from what you say that you are talking about a pet african pygmy hedgehog, but please correct me if I’m wrong. If I’m right then this site is about wild European hedgehogs, which might be why no-one replied sooner. Regardless of that, it sounds as if the hedgehog needs help from a vet. Although you talk about medication being administered, so maybe you have already taken your hedgehog to a vet?
I hope you manage/d to get help for the hedgehog and things have improved. Good luck.
