I really can’t stress enough how important it is for this hedgehog to be seen by a rescue. Please get in touch with the BHPS or ask your local sanctuary for any others in the area.
If you tell us whereabouts you are, it may be that another rescue or linked carer can at least check it over and find out what parasites it has, sort out treating them, even if you have it to feed and look after due to lack of space in the rescues.
Not all rescues/carers are registered with the BHPS. Please also call round local vets as there are often rescues/carers who they will have details of. Vets who don’t treat wildlife on an ongoing basis will know which vet in the area does.
If your hedgehog has parasites (and it almost certainly will), unless these are treated it is likely to go downhill and eventually become visibly ill and unless treated before that point almost certainly will not survive despite your care.
If it’s not hibernating but not eating or drinking then it is going to be very poorly indeed. Hibernating hedgehogs do not feel warm to the touch.
