[He tries to huff out something like "well, can't really go anywhere" but he coughs, instead, and watches the water out of the corner of his eye, glowing over him as he starts to feel a lot better. It seems he had several broken bones, along with many cuts and bruises and slight frostbite, so Korra does have a lot to heal there.]
