I've had 5 concussions, right fibula break 3x and left 2x, torn cartilage in bottom 4 ribs (left side) severe bruising to bottom 3 and torn upper abdomen in the same accident, total of 4 broken bones to the right hand and surgery once to the same hand, broke both feet at the same time and had no feeling for 2 weeks up to my knees and little feeling up to my hips, separated left shoulder, hyper extended back with sprain neck..... basically you have to make your body parts move. Just remember how to do things and focus on moving those body parts.
What does your physician tell you? Something like this you should not blindly ask a community and expect accurate advice. I can give you my experiences with fractured rib, concussions, broken bones, and pinched nerves but none of that relates to you.
Ask your dr. what you can and can't do
