Danny can heal with the Iron fist and it's a shame to not see that ability used more often, especially because he has friends who get their asses kicked regularly. So, five times Danny healed one of the Defenders or closed allies, and one time they took care of him.

Ideas to consider:

+ Luke has bulletproof skin but blunt trauma can still cause internal damage or shattered bones.

+ Using his chi to heal drains Danny of energy considerably, he's prone to pass out or sleepily curl up next to the person he just healed. Please, someone bring this kid a blanket.

+ Alternatively, Danny needs to eat a lot to get some of his energy back.

+ If it happens during a fight, there's no way he can protect himself later if he can barely stand up. Some backup is welcome.

+ Danny knows now that Jessica doesn't like being touched so he needs to be extra careful around her when she get hurt/poisoned and needs a fist hand.
