Oh, yes, he may need just a general check and a little care. I expect his lightsaber wounds are basically sealed by the cauterizing effect but will be tender. He could have internal bleeding or an open injury from the bowcaster, which if he's stitched up (or otherwise sealed in some way) may require him to take it easy and it can then heal on its own. I don't think it was life threatening to him unless completely unattended to.
