Workouts meals and supplements after a whipple

Hey out there. I am looking to get help from anybody out there that knows about or has had a whipple. In 2014 i was in a accident. It broke my back, ribs, clavicle and did a ton of internal damage. I was wondering if anybody out there knows any good work outs, diets and supplements i can take. My diet is high protien low carb and sugar. Its difficult to find things that work on a consistent basis and dont hurt my gut as far as diet goes. I also have a hard time with workouts because most times before i can even break a sweat I will pull or strain muscles in my chest shoulders and back. Just looking for some insite from anyone with exp. Thanks all have a great day
