Short answer
For most back and neck pain, use whichever feels better. Heat tends to help stiffness and muscle spasm, and has some evidence for short-term relief of acute low back pain. Ice can numb a fresh, swollen injury such as an ankle sprain. Neither fixes the problem on its own; movement and gradually loading the area do that.
Common causes
Heat
Best for stiffness, spasm and that “locked up” feeling. 15–20 minutes, never directly on skin, and never while sleeping.
Ice
Best for a fresh knock or sprain with swelling. 10–15 minutes wrapped in a cloth.
Either
For a stiff neck or sore back, comfort is the goal. If one makes it worse, switch.
