What should be the first action when providing first aid for a strain?

When addressing a strain, the initial action should be to rest the affected muscle. This approach is vital because it prevents further injury and allows the muscle to begin the recovery process. Resting helps to minimize swelling and pain, giving the body time to heal effectively.

Once the muscle is rested, further steps such as ice application, compression, and elevation might follow to manage symptoms. Movement or massage might not be suitable at the outset because they could exacerbate the injury or lead to more pain and damage. Therefore, prioritizing rest is essential to ensure a proper healing process and reduce the risk of complications.
