He says he feels no pain, just as if his leg 'gives way'/decreased power. He gets pain on the medial side of his ankle but i think it's from the immobility. He doesn't get a noticable drop, but I'll check Trendellenburg. He keeps his affected leg abducted when he walks (without moonboot), as if he can't bring his hip in (?). So he puts his foot down outside his normal BOS. Thanks very much for replying!!
