Well, from what I can tell, yes. I'm taking this from episode one of the second season when Ayato ate Touka's and she was screaming in pain the whole time. Sooo yeah. It probobly hurts. However, there is also evidence to the contrary, like in tokyo ghoul Jack OVA, Minami's Kagune was impaled, but she seemed generally unnafected. I think it varies from Ghoul to Ghoul.
