How Long Should Ice Be Used To Reduce Swelling? Apply an ice or cold pack right away to prevent or minimize swelling. Apply the ice or cold pack for 10 to 20 minutes, 3 or more times a day. After 48 to 72 hours, if swelling is gone, apply heat to the area that hurts.
How Many Days Should I Ice An Injury? If an injury has occurred to any body part within three days, ice is preferred — 20 minutes on and 30 to 40 minutes off. Pain to the back, neck and large muscle groups like quads, hamstrings and calves will respond well to heat after three days
Is Icing An Injury Still Recommended? Ice treatment is most commonly used for acute injuries. If you have had a recent injury (within the last 48 hours) where swelling is a problem, you should be using ice. Ice packs can help minimize swelling around the injury, reduce bleeding into the tissues, and reduce muscle spasm
