Ice pack work: Cold packs are very effective at reducing swelling and numbing pain. An injury swells because fluid leaks from blood vessels; reducing their tendency to ooze. The less fluid that leaks from blood vessels, the less swelling results.

Gel packs better than ice: With most injuries involving the back, gel packs are easy to use. Ice bags are better for ankles and knees for a longer cold period. Strengths: Cold gel packs contain a special gel that can be frozen and refrozen.

Ice pack good for back pain: In most instances, you should use ice on your back for the first24 to 72 hours following an injury. Cold therapy helps minimize swelling and inflammation. This, in turn, eases your pain. Cold therapy may also decrease tissue damage.
