I have looked after and encouraged the hedgehogs in my garden for a number of years and rescued a few sick and injured ones as well as a couple of under-weight juveniles but have always taken them to local experienced carers. They are the ones who can check for lungworm burdens etc and treat them and get them to vets with an interest in hogs if required.
I would never attempt to do it myself as I just don’t have the facilities and experience and the hedgehog is best off in the right hands for over-wintering and treatment when required. I’ve had hedgehogs returned to me after successful treatment and released them back into my garden where there are hog houses as well food and water and all went well. Probably the rest route for hedgehog… and human rescuer!
