After proper rest, one of the first and simplest ways to treat a pulled muscle is to apply an ice pack to the affected area. The step is effective in constricting the inflamed blood vessels, and reducing blood flow to the area. In this respect, icing actually prevents further muscle damage and speeds healing.
To use, wrap a handful of ice cubes in a thin towel. Apply the ice pack to the torn or strained muscle. Keep in place for about 15 minutes. Repeat application every two hours for the first 24 to 72 hours.
