2. Use Cold
Cold is an effective way to reduce swelling as a result of knee bursitis. Cold compresses are used for sports injuries and swelling in general, and bursitis is no exception. Ice, in addition to elevating and resting the knee, can reduce discomfort quickly. While you are resting or elevating your knee, apply ice packs to the affected area at least 3 or 4 times a day for a few minutes to half an hour.
You can reduce the number of treatments with the ice pack as you start feeling better and as the swelling subsides. If you find ice packs uncomfortable, you can take a plastic bag of frozen vegetables and apply them to the area as long as the contents remain icy. Although ice is a great way to neutralize pain and reduce swelling, you should avoid putting actual ice cubes directly on the knee.
