"You're the limb I've lost but somehow I still feel." To be literal, what this means is like a phantom pain. Literally, people who lose a limb can (but not necessarily) feel random pains in places where they no longer have a body part. To apply it to the song, I think it means someone leaves and you'd expect that their absence would take away all thoughts and feelings of them, but it didn't. Also, it most likely is "hellish shoal." That makes the most sense. The only other thing it could sound like is "hellish hole," which makes less sense.
