Hello Timmy. You could do some joint-freeing poses from the so called Pawanmuktasana series. It includes simple stretches for the neck, wrists, elbows and shoulders. Sit on the floor (close to a wall for support, if you prefer) or sit on a chair or on the bed, keeping your spine upright.
1. Extend your arms in front of you at shoulder level, relax your shoulders and rotate your wrists, first in one direction, than in the other.
2. Then keep the arms as in pose 1 and bend the elbows, bringing the palms to the shoulders.
3. Then place the fingers on the shoulders and fully rotate both elbows in large circles from the shoulder joint, in both directions.
4. Then bring the arms down, rest them on your knees or in your lap and slowly move the head up and down; then ear to shoulder; then turn the head to one side keeping the chin parallel to the floor; always going to both sides. Finally, you can try a complete circle with your head but do not crunch the back of the neck too much.
You can do between 5 to 10 repetitions of each, depending what feels good to you.
Try to do all the exercises slowly and mindfully, breathing deeply and really focusing all your attention on these movements.
My experience is that our injuries are our great teachers, and usually come when we need to stop and rest.

While you can't move your foot you could also explore some meditation techniques.
