I'm sorry your boy is so sick, but this is not WHS. It sounds like he has a respiratory infection, or possibly heart failure which can also cause respiratory symptoms.
If this is a URI, with antibiotics and supportive care he can recover. If it's gone to pneumonia, it is much more difficult to cure. The vet sells foods made for syringe feeding which would provide him with the nutrition he requires. Hills A/D or Clinicare are both usually well liked by hedgehogs.
Any illness in a hedgehog can cause mobility issues and leg weakness.
I'm moving this out of the WHS forum.
