Home Treatment Home Treatment If your bruise does not require an evaluation by a doctor, you may be able to use home treatment to help relieve pain, swelling, and stiffness.

Rest and protect a bruised area. Ice will reduce pain and swelling. Apply ice or cold packs immediately to prevent or minimize swelling.

Apply the ice or cold pack for 10 to 20 minutes, 3 or more times a day. For the first 48 hours after an injury, avoid things that might increase swelling, such as hot showers, hot tubs, hot packs, or alcoholic beverages. After 48 to 72 hours, if swelling is gone, apply heat and begin gentle exercise with the aid of moist heat to help restore and maintain flexibility. Some experts recommend alternating between hot and cold treatments. Compression , or wrapping the bruised area with an elastic bandage such as an Ace wrap , will help decrease swelling.

Don't wrap it too tightly, as this can cause more swelling below the affected area. Loosen the bandage if it gets too tight. Signs that the bandage is too tight include numbness, tingling, increased pain, coolness, or swelling in the area below the bandage. Talk to your doctor if you think you need to use a wrap for longer than 48 to 72 hours.

To find the cause of your bruising, your doctor might check your blood platelet levels or do tests that measure the time it takes your blood to clot.
