Kylo was injured pretty badly even before the fight with Finn and Rey. They made a point of showing the blood on the ground before the fight, and having him beat his chest to pump himself up to get through the pain. My take on it is that he was using a big chunk of his force powers just being able to walk, let alone fight. Rey may not be trained in using a lightsaber, but they did show her being proficient with her staff weapon.

About Rey..good point. Does make her fighting abilities in that situation seem a little less farfetched.
