Actually during his training to remove his limiters he has gotten hurt, since he continued to train even though his bones were pretty much broken at one point.

He isn't technically invulnerable persay, its more like his body has just toughened to the point were he is numbed to most kinds of damage rather then straight out indestructible.

Its similar to Shizuo Heiwajima from Durarara, as his bones have been broken so many times they simply don't break anymore, but as a side effect he doesn't or can't really feel damage or pain ever again.
