I had an epi and no back problems from that. However, if they took fluid from the spine then yes, that hurts a lot and you can feel bruised for 6-8 weeks (from memory). It really is a killer and he needs rest time - not easy when you need help with your pregnancy and DD, but even things like walking or moving his arms can hurt, depending on where/how it was done. At least he can have painkillers!
