Surgery - Only One Command

Hello! Today, I've made surgery in Minecraft! Now you can break bones, so I wouldn't recommend this if your just playing on a survival world. It's mostly for roleplay maps.

Click here for the command!

Tutorial:
Now, when you get hurt in any way, you will damage one of the four body
parts: your head, your body, your legs, and your feet. when a body part
gets damaged, it will tell you in chat, and there will be "pain" particles around
the body part as well. But be quick! If you leave a broken bone for too long,
you will be killed. Make sure you have casts at need. Only the cast for your
broken body part will fix it. When you have your cast on, you will regain health.
When holding your syringe, look down to use them. But, the Poison Syringe
will kill you, so make sure you know what your doing! The Health Syringe will
regenerate all your health, and the Pain Reducer Syringe will stop the pain effect,
like a cast would. And finally, when wearing a full Surgeon Suit, you will be resistant
to the germs the players with broken bones carry around them!
