Answer to Question 1
The PRICE prescription for treating an injury resulting from exercise suggests that you:
Protect the area with an elastic wrap, a sling, splint, cane, crutches, or an air cast.
Rest to promote tissue healing. Avoid activities that cause pain, swelling, or discomfort.
Ice the area immediately (but not directly on the skin), even if you're seeking medical help. Repeat every 2 or 3 hours while you're awake for the first 48 to 72 hours. Cold reduces pain, swelling, and inflammation in injured muscles, joints, and connecting tissues and may slow bleeding if a tear has occurred.
Compress the area with an elastic bandage until the swelling stops. Begin wrapping at the end farthest from your heart. Loosen the wrap if the pain increases, the area becomes numb, or swelling is occurring below the wrapped area.
Elevate the area above your heart, especially at night. Gravity helps reduces welling by draining excess fluid.
After 48 hours, if the swelling is gone, you may apply warmth or gentle heat, which improves the blood flow and speeds healing.
