Cold therapy is highly recommended for treating different muscle injuries, especially leg muscles. The best thing about applying cold therapy to the legs is that it’s both inexpensive and accessible to any patient. When cold therapy is applied to the injury for 15-20 minutes at a time, it causes the blood vessels to tighten which lessens blood flow in order to help reduce swelling and pain in the area. It is a great treatment option, along with rest, compression, stretching and advice from a sports medicine professional.
