A square of vinyl siding is equal to 100 square feet. 10 foot by 10 foot = 100 square feet (10' x 10' = 100 sq ft).
For acute injuries, you may have to stay off your feet as much as possible or even use crutches for a short time. Ice. Put ice on your knee for 15 to 20 minutes a few times each day. Use ice cubes or a bag of frozen vegetables wrapped in a towel. Compression. Wrap an elastic bandage around your knee to help control swelling. Make the bandage fit snugly around your knee, but not tight enough to cause pain or leg swelling.
Injecting medications directly into your knee might help in certain situations. The two most common injections are corticosteroids and lubricants. Corticosteroid injections can help arthritis and other inflammations of the knee. They usually need to be repeated every few months. Lubricants that are similar to the fluid already in your knee joint can help with movement and pain.
