Why yes! As a matter of fact, I do.

• Jason lost a kidney during his Robin years. It wasn’t a huge deal, because you only need one, but here’s the interesting bit– the Lazarus Pit may or may not have grown the second one back. He honestly doesn’t know. The possibility didn’t occur to him until years after his resurrection, and then he just… decided not to check. It’s more fun that way, apparently.
  
• Stephanie wears wrist braces whenever she can get away with it, especially when she’s typing. Her nerves are damaged from the time Black Mask chained her up and tortured her (War Games), so she has trouble with delicate movement. Sometimes her fingers go numb. 
• Bruce has been pieced back together so many times that he gets stopped at metal detectors– too much bone fracture repair. He has plates all over, but the most prominent metalwork is a screw sticking out of his elbow. He tells people that he broke it in a car crash. He’s lying.
• Cass has scars everywhere, but the most noticeable is a bullet hole in her calf. She’s missing a chunk of the muscle, so she has to hide it in public. (That’s incidentally the reason full length dresses made a comeback in Gotham fashion). One of her fingers is crooked from a badly healed break.
• Tim gets chronic headaches. He’s not sure if it’s a physical injury or a stress symptom, but either way, it hurts a lot. He does a lot of his work in the dark– just the computer screens– because bright light makes it worse.
• Dick’s shoulder has been hurting him since his first year on the job, so long that he doesn’t really notice the pain anymore. It’s the worst in the morning, when he first starts moving. Getting up gets hard.
• Damian gets phantom pains in his chest. He knows it’s a psychological thing– from getting impaled and dying– but it makes it hard to breathe sometimes, especially when he’s trying to sleep. He gets up and wanders around the house whenever it happens.
