The most important thing when you return most likely will be choosing your training partners wisely.

Don't roll with strangers or lower heavier belts that don't know how to roll properly yet especially since your a Black Belt. A lot of lower belts can't help themselves but to try to go extra hard against black belts.

And if say you have a really bad wrist and you no longer wear anything to protect it you should wear something probably just to remind people that oh there's an injury in that spot. Just to give them a constant reminder.

Yeah, it's all about doing the things that allow you to leave the mat if not better then at least as good as you stepped on it :) Anything that has significant risk of doing the opposite (makes you worse off) should be kept away.

I cannot say I have something similar! You have been through hell and back, god bless you and welcome back!

In 2014 I had a nasty injury on my right hand. My thumb tip was held on by skin only, bone was intact and nerves and tendons were cut. My pointer and middle finger were worse, fracture bones, both extensor and flexor tendons were severed. The pointer was split from the tip thru the first joint and about 1/4 the way to the second joint. The only finger that was not damaged was my pinky. Had major surgeries to fix and repair as much as possible.

I decided that Physical therapy had progressed to a point where I could do more myself. During this time I had been sitting on the corner of the mat watching practices as much as I could. When I came back I still had restrictions of using my hand, because of pins still in two fingers. Working with a select few at the gym we came up with a plan to allow me to work. sticking my right hand into my belt and modifying moves based on restrictions I had. using this method i was able to continue to progress where I know have no restrictions at all.

I think as others said above, the goal here is for you to relearn your body and limitations, within your injuries. Take it slow listen to how you feel, and do not overdo it.

Good luck !

So much respect for people like you!
I Hope you keep improving and reach your new goal. Greeting from Switzerland

I plan on wearing an orange Gi tonight to class, so I expect to have a simular list of imjuries.
Massive congrats on clawing your way back, I hope you never have to go though anything like that again.

wow, thats horrible that you had to deal with that but God bless ya for getting back to where you are. The one thing I found with my knee surgery (and is clearly a drop in the bucket compared to your long list of issues and surgeries sir) is that by working with only higher belts I knee even though they'd put me in situations I didn't want to be in (they knew the knee was weak, so they "lovingly" attacked the knee over and over with knee bars and making me shrimp and work without there being real "danger" to it. By a 3-4 months later my knee wasn't something I thought about but what I was working on etc.

I hope you can continue to teach and get even better from these injuries, and you are right, after so many years doing martial arts it is who we are, not something we do, so I know you'll figure out a way around this.

Go slow and make sure you pick your partners carefully, and as counter-intuitive as this is, go slow. Rushing back will only knock you back further.
