When someone gets injured, the acronym RICE is often what is instructed. Rest, Ice, Compression, and Elevation. While the R, I, and E are pretty self-explanatory, the C for compression may need a bit of explanation.
Compressing an injured or swollen area helps to reduce inflammation by physically pushing the fluid out of the area. The problems, however, arise with the improper application of the compression. The most common type of compression is wrapping an ACE bandage around the affected area. The key is to not put it on too tight and to start from the furthest part and wrap it towards the body. Another popular compression technique is a brace or sleeve.
Some signs to watch for that will indicate the compression is too tight is tingling, numbness, a cooling of the skin, swelling, or increased pain below the site of the compression. If this happens, simply loosen the compression until those signs and symptoms are gone.
