Can ran over my foot, arm feels tight.

One of my feet got ran over by a car today . The toes didn't suffer any damage, but the middle portion of my foot is hurting quite a bit. I have difficulty in walking, and i walk with the support of a stick. It was a medium weight 4 seater car. The car was reversing at slow to medium speed and i got ran over by the rear wheels. I also fell because of the impact and my wrist twisted when i landed. Since then my arm is feeling quite tight, like after a heavy workout. I went to the doctor, did the X-ray. The X-ray was fine, no fracture. The doc told me to app ice packs ond the foot and to rest for at least 2 days. He prescribed me Myogrip(Diclofenac Potassium & Trypsin-Chymotrypsin) & Cyra 20(Rabeprazole sodium) tablets for five days, with myogrip twice a day, and the other one once a day. Apart from following the usual RICE method for foot injuries, what should i do. Also,please suggest something for my arm, the tight feeling has persisted.
